I also support not limiting the content type. I can imagine implementing 
a search extension to existing XML based protocols.

RFC5323 Section 3 say's

    Clients can determine which query grammars are supported by an
    arbiter by invoking OPTIONS on the search arbiter.  If the resource
    supports SEARCH, then the DASL response header will appear in the
    response.  The DASL response header lists the supported grammars.

    Servers supporting the WebDAV extensions [RFC3253  <https://tools.ietf.org/html/rfc3253>] and/or [RFC3744  <https://tools.ietf.org/html/rfc3744>]
    MUST also:

    o  report SEARCH in the live property DAV:supported-method-set for
       all search arbiter resources, and

...

Presumably a WebDAV compliant client knows whether or not SEARCH is 
supported as a WebDAV service

So:

If it's in DAV:supported-method-set it's WebDAV SEARCH

If it's in the "Accept-Search" Header Field it's the new SEARCH

and you can't have both. No need to parse the content.
