That's a good point, considering the lack of an HTTP method registry.

Which, as a matter of fact, is an open issue for HTTPbis.

No, discovering Allow: PROPFIND should be sufficient, just as it is for 
header names and status codes defined in WebDAV (these have IANA 
registries).

Right, it doesn't matter in practice (*smiles and ducks*).

But as it matters in theory, and we take internet protocols seriously, 
we'll be adding the missing registry (see 
<http://www3.tools.ietf.org/wg/httpbis/trac/ticket/72>).
