I’m doing a 508/WCAG scan of my site and using the W3C Nu HTML checker. I’m getting two errors both related to unallowed attributes on div elements related to Better Exposed Filters.

1. Attribute novalidate not allowed on element div at this point.

<div class="views-exposed-form bef-exposed-form search-form block block-views block-views-exposed-filter-blocksearch-resources-page-1" novalidate="novalidate" data-drupal-selector="views-exposed-form-search-resources-page-1" id="block-exposedformsearch-resourcespage-1-2">

2. Attribute name not allowed on element div at this point.

    <div data-drupal-selector="edit-sort-bef-combine" id="edit-sort-bef-combine--2" name="sort_bef_combine" class="form-select bef-links">
      <ul>
        <li><a href="/technical-assistance-resources" id="edit-sort-bef-combine-search-api-relevance-desc" name="sort_bef_combine[search_api_relevance_DESC]" class="bef-link bef-link--selected">Relevance</a> </li>
        <li><a href="/technical-assistance-resources?sort_bef_combine=field_posted_date_DESC" id="edit-sort-bef-combine-field-posted-date-desc" name="sort_bef_combine[field_posted_date_DESC]" class="bef-link">Posted date (newest first)</a> </li>
        <li><a href="/technical-assistance-resources?sort_bef_combine=field_posted_date_ASC" id="edit-sort-bef-combine-field-posted-date-asc" name="sort_bef_combine[field_posted_date_ASC]" class="bef-link">Posted date (oldest first)</a></li>
      </ul>
    </div>

I’m not certain these are actually coming from BEF, I couldn’t find any references to these when searching the BEF code or the issues queue on the project page.

Any ideas? And should I consider this a failure for the WCAG parsing requirement?
