question about "xsltTransformation" property in DAML-S 0.9+

dear DAML-S researchers,

i would like to compile a brief comparison of the various existing
approaches for mapping between DAML+OIL(OWL) and XML, and of course i am
very interested to learn about the mapping concept envisioned for DAML-S
0.9

Does there exist an example/explanation of the "xsltTransformation"
property, or is this work in progress?
To discuss the various problems (and solutions) of the XSLT based mapping,
I have written a (very simple) example,  a mapping of a DAML+OIL  "purchase
order" to some XML represention.

The example is available online:
http://sws.mcm.unisg.ch/mapping/po.daml (the DAML+OIL ontology; the XML
schema is http://www.w3.org/TR/xmlschema-0/#po.xsd)
http://sws.mcm.unisg.ch/mapping/po.xml  (an instance of the XML schema)
http://sws.mcm.unisg.ch/mapping/po_instance.rdf  (an instance of the
DAML+OIL ontology)
http://sws.mcm.unisg.ch/mapping/PO-daml2xml.xsl  (the XSL stylesheet which
maps from ONE RDF/XML representation to XML)

Of course i do not know if this is compatible with the current ideas
regarding the "xsltTransformation" property ;-)

However, the example illustrates some open issues/some of the questions i
currently have:

*  a DAML+OIL concept can have multiple RDF/XML representations => Q: Do
you plan to impose some guidelines which restrict the use of certain RFD
abbrev. syntaxes, or do you think it's the responsibility of the softare
agents, to figure out how _exactly_ the mapping should be carried out ,
e.g. to figure out which RDF/XML style is used,  etc.
* XSLT Transformations are not bi-directional => Q: will the stylesheets
for inputProperties look different than those for outputProperties?

thanks in advance,
joachim
