               Microformats and microdata have a limited notion of <a>entity</a> identity: entities may have identifiers (in microdata, from the <code>@itemid</code> attribute) but these are not used within the data model to combine entities or link them together into graphs. Syntax-neutral <a title="vocabulary">vocabularies</a> use the RDF concept of identity whereby entities with the same identifier are the same entity, and references to that entity's identifier serve to create a graph of entities. This should be reflected in the definition of the microdata variant of the vocabulary, which should allow <code>@itemid</code> on all items, and specify that consumers should combine and link to items to create a graph.
