Re: [Gen-art] review of draft-levin-mmusic-xml-media-control-12.txt

Roni:

I have check the schema and the first example, and they validate with no 
errors. However, I am surprised to see that:

a) the schema does not define a target namespace
b) the examples do not include a target namespace

without these two, I think it is not possible to correlate an example 
with a schema. I don't know how Xerces does not report an error, but all 
the other XML schemas and documents that we have in SIMLE, for example, 
contain target namespaces.

c) There is no IANA registration of the URN namespace (well, that is 
consistent with the absence of a namespace, but I think it should be 
present).
d) There is no IANA registration of the XML schema.

Well, I think you should contact the IETF XML Directory and ask for a 
review. I don't consider myself an XML expert... just someone who has 
been playing around with it.
