This vocabulary, a part of EPUB® 3, defines a set of properties relating to the description of structural semantics of written works. While the vocabulary is generally host language agnostic, it has been constructed primarily to enable semantic inflection of elements in the HTML vocabulary.
The HTML usage context fields indicate contexts in HTML5 documents where the given property is considered relevant. When processing HTML5 documents, Reading Systems may ignore properties that occur outside the specified usage context, unless the usage context is explicitly overridden or extended by the host specification.
Changes to this vocabulary will only occur in conjunction with revisions to the EPUB suite of specifications. Terms in the vocabulary may be deprecated as the result of a revision, but will not be removed.
New terms may be introduced at any time for experimental purposes. All such terms will be marked with the label [experimental]. Experimental terms are subject to removal at any time, and may remain designated as experimental across revisions to the EPUB specifications.
