I think the best way is to send this kind of feedback/questions to the DASL
mailing list (<:
http://www.w3.org/pub/WWW/Archives/Public/www-webdav-dasl/>), which I'm
cc'ing.

It does. <prop> is just inherited from RFC2518
(<http://greenbytes.de/tech/webdav/rfc2518.html#ELEMENT_prop>). It allows to
supply multiple property elements, such as

<prop xmlns="DAV:"><getcontenttype/><getcontentlength/></prop>

Not yet. How do others feel about it? I guess the original authors wanted to
keep DAV:basicsearch as simple as possible, thus the restriction to a single
scope.

No. DTDs in WebDAV specs aren't used for validation (in fact, they can't be
used for validation). The SEARCH spec probably should clarify the role of
the DTD fragments similar to what the ordering spec already does:

<http://greenbytes.de/tech/webdav/draft-ietf-webdav-ordering-protocol-10.htm
l#rfc.section.1>


Hope this helps,

Julian
