Re: Issue 5.17 XML presentation syntax for OWL (in UML)

I have confirmed that there was no problem for the latest version of the
XML Schema for OWL [1] to parse a sample document [2] with XML Schema
validation by using Xerces Java v2.2.0 XML parser [3].  Attached below is a
PDF file that includes UML class diagrams of the XML Schema for OWL [1].
The mappings from XML Schema to UML are for the most part followed by the
ways proposed in [4].

(See attached file: OWL-Schema-in-UML.pdf)

I'm leaving this in for now, for purposes of symmetry.
