Pull request overview
This PR implements comprehensive validation for the <alternatives> element according to SciELO Brasil specifications, significantly expanding validation coverage from 40% to 100% by adding four critical validation rules for SVG format requirements, accessibility attribute restrictions, and version completeness checks.
Changes:
- Added 4 new validation methods: SVG format enforcement, alt-text prohibition, long-desc prohibition, and both-versions presence checking
- Extended support from disp-formula to include inline-formula elements
- Implemented complete internationalization with advice_text and advice_params for all validations
- Added 30 new test cases across 5 test classes covering all new validation scenarios

There was a problem hiding this comment.
The validation methods have inconsistent behavior regarding when they yield results. validate_svg_format and validate_expected_elements always yield a result (OK or error), while validate_no_alt_text and validate_no_long_desc only yield when there's an error (early return when valid at lines 134 and 180). This inconsistency makes it harder to track which validations were performed. Consider making all validation methods either always yield a result or consistently only yield on errors, and document this behavior clearly.

The docstring states formulas (dict): Dictionary of formulas... but the actual implementation (lines 321-324) assigns a chain iterator to self.formulas, not a dictionary. Update the docstring to accurately reflect that formulas is an iterator that yields formula data dictionaries.

There was a problem hiding this comment.
The original detailed assertions in test_validation_success were replaced with a simple check that some OK validations exist (lines 44-46). The original test verified the complete structure of validation responses including all fields (title, parent, item, expected_value, got_value, message, advice, data). This significant reduction in test assertions means important fields could be broken without tests catching it. Consider keeping at least some structural validation to ensure response format remains correct, or add a separate test that validates response structure.

There was a problem hiding this comment.
The validation for both versions checks if coded_version in elements (line 241) but for formulas, it also has a fallback check for "tex-math" on line 243. However, this logic doesn't account for the fact that in the test parameters (line 395 in test file), the MathML math element is passed with the full namespace {http://www.w3.org/1998/Math/MathML}math. The validation will work correctly, but there's an inconsistency: the code expects the namespace in parameters but checks against elements list which also has namespaces. This is correct but could be clearer with a comment explaining namespace handling.

There was a problem hiding this comment.
The test cases check that validations exist and have certain responses, but they don't verify the actual count or structure of all validations. For example, in test_svg_format_valid, the test only checks if SVG validations exist and if they are OK, but doesn't verify that all OTHER validations (alt-text, long-desc, both versions) also pass. A valid XML should generate OK responses for all 5 validation types. Consider adding assertions to verify the complete set of expected validations.

There was a problem hiding this comment.
The test assertion self.assertIn(validation['response'], ['OK', 'ERROR']) on line 326 is too permissive. For a test case where both versions ARE present (as indicated by the test name and XML), all validations should return 'OK' status, not 'ERROR'. This assertion would pass even if the validation incorrectly returned an ERROR. Change to self.assertEqual('OK', validation['response']) to properly validate the expected behavior.

There was a problem hiding this comment.
The self.formulas attribute is assigned a chain iterator (lines 321-324) which can only be consumed once. If the validate() method is called multiple times on the same AlternativesValidation instance, the second call will not validate any formulas because the iterator is exhausted. Consider either: (1) converting to a list if multiple iterations are needed: list(chain(...)), (2) making formulas a property that creates a new chain each time, or (3) documenting that AlternativesValidation instances should only be used once.

The original detailed assertions in test_validation_children_fail were replaced with basic checks (lines 81-87). Like test_validation_success, this test previously verified the complete validation response structure. The new assertions only check that errors exist and that 'graphic' appears in some advice text. This doesn't verify the error structure, message format, expected/obtained values, or that all validation types run correctly. Consider restoring some structural assertions or adding helper methods to validate response format consistently.

There was a problem hiding this comment.
In validate_svg_format, the code converts graphic_href to lowercase for comparison (line 95: graphic_href.lower().endswith('.svg')), but the error message uses the original case (line 106-107). While this is not necessarily wrong, it could be confusing if someone has a file named "tabela.SVG" (uppercase extension) - the validation would pass but the case inconsistency might confuse users. Consider clarifying in the advice text that the check is case-insensitive, or normalize the extension in the output message for consistency.

validate_both_versions_present() treats alternative_elements == [] as an error (missing both coded + image), which will flag every element that doesn't use (valid cases according to existing validators like FigValidation/TableWrapValidation). This should only enforce "both versions" when is actually present; otherwise skip to avoid false ERRORs.

validate_no_alt_text() determines validity via is_valid = not alt_text, but alt_text is sourced from .text in the models; <alt-text/> (present but empty) yields None and will incorrectly pass.

validate_svg_format() currently uses alternative_data['graphic'] and will run even when the parent element has no (e.g., a with only , or a with only

AlternativesValidation.init mentions making the instance reusable by converting formulas to a list, but figures and table_wraps are still generators (see fig.ArticleFigs.get_all_figs / tablewrap.ArticleTableWrappers.get_all_table_wrappers). After one validate() call those generators will be exhausted, so the instance still isn't reusable. Consider materializing figures/table_wraps as lists too (or regenerating them per validate()) if reusability is a goal, or adjust the docstring/note accordingly.
