6. XHTML Attribute Collections

This section is normative.

Many of the modules in this document define the required attributes for their elements. The elements in those modules also reference zero or more attribute collections. Attribute collections are defined in their own modules, but the meta collection "Common" is defined in this section. The table below summarizes the attribute collections available.

Note that while these Collections are referenced throughout this document, these expressions should in no way be considered normative or mandatory. They are an editorial convenience. When used in this document, it is the expansion of the term that is normative, not the term itself.

For the avoidance of doubt, if an attribute collection is referenced by an element's definition, and an attribute in that collection is also explicitly referenced by that element's definition, this does NOT cause a conflict. It is up to the schema implementation to update the content models accordingly.
