Can you send me the atom & app as rng xml notation if you have the tools set up?

It is definitely of interest, not sure if it is an issue.  These XSDs won't parse atom entries without the cmis terminator tag due to the xs:any issue and unique particle issue.  However, CMIS does not mandate that these are used.  Clients/Servers could try with these XSDs if CMIS.  If that does not succeed, try with normal atom XSDs.  Definitely not ideal.

The spec states it is repository specific what happens when a non atom entry media type or atom entry media type without cmis info is POST'ed to a collection.  It suggests that the repository may create an instance of a document of a default type.

That is in the children's POST section.

I use James Clark's "trang".... The following seems to work just fine:

(1) saxon http://greenbytes.de/tech/webdav/rfc4287.xml 
extract-artwork.xslt name=collected-grammar.rnc > rfc4287-grammar.rnc

(2) java -jar trang.jar  -I rnc -O rng rfc4287-grammar.rnc 
rfc4287-grammar.rng

Now that's the issue. When you use them to *parse*, do the behave 
correctly with respect to the extensibility rules?
