Description Torkild Resheim

The OPF specification (http://idpf.org/epub/20/spec/OPF_2.0.1_draft.htm#Section2.3.1) states that fallback items must be specified for items that are not in the list of OPS core media types. There could for instance be a PDF representation of a page and a XHTML 1.1 representation of the same page. The latter is a core media type. Reading systems that does not support PDF would use the HTML version.

The data model has support for fallback items, but the Ant task and API does not. As it is desirable to have full support for all EPUB 2.0.1 features, this should be added.

Additionally an error must be flagged when an item *not* a core media type is added and a "fallback" attribute pointing to a legal item's identifier is not present. The fallback item may be added after the preferred item so the validation must be performed at package time.

A list of core media types is here: http://idpf.org/epub/20/spec/OPS_2.0.1_draft.htm#Section1.3.7
