4.2.2.1 manifest.rdf, mandatory or not ?

Proposal: Adapt third paragraph of 2.6 to: All metadata files of a document or sub document shall be listed in a separate metadata manifest file, which has the file name "manifest.rdf". This file enumerates the metadata files that are contained in document or sub document and their relationships to other files in an OpenDocument package. See chapter 5. Each document or sub document shall have its own "metadata.rdf" file. Add a new paragraph to Part3, Section 2.6, behind the third paragraph: In addition to metadata files, the "manifest.rdf" files may list other files which are contained in the document or sub document that contain RDF metadata, like files that contain RDFa metadata. The "manifest.rdf" file need not exist if a document or sub document does not contain any files that contain RDF metadata. Change 2nd paragraph of section 4.2.1 (part 1) to: In addition to the mechanism defined in Part 3 of this specification ** RDF metadata can be attached to elements in the "content.xml" and "styles.xml" file. Elements supporting this kind of metadata have the following attributes: xhtml:about 19.907, xhtml:property 19.910, xhtml:content 19.908, and xhtml:datatype 19.909. When metadata is added using these attributes, it is referred to as in content metatada. "content.xml" and "styles.xml" files that contain in content metadata shall be listed in the package's "manifest.rdf" file.
