My apologies. I've since remembered XHTML Modularization 1.0 does indeed make reference to the value attribute of the li element; it can be found in the Legacy Module. I'd consequently like to withdraw my previous comment to www-html-editor.
I do note, however, that both XHTML Modularization 1.0 and XHTML Basic 1.1 are delta specifications that normatively incorporate from the HTML 4.01 Recommendation. It could save confusion if a future XHTML Modularization 1.x document were created as a merged (non-delta) specification, without having to refer to HTML 4.01. Such a document could draw on the role/RDFa/access/inputmode modules, too.
Thank you, Dave
