Re: DAV Versioning DTD.

Dear Geoff,

Here is the new proposal for expand-properties.  It has the advantage over the
current version of not overloading the prop semantics.  Structure information
is conveyed via the prop-apply and multiprop tags in the request and response
respectively.  Note that they can only be used for properties that contain
hrefs.  These examples verify against my latest DTD which I will send after
this.  Note also that the example in version 12 and 12.1 of the specification
returned erroneous values for creator-displayname.  That is fixed below.

Sincerely,
James
