Hi, everyone. I didn't get any responses earlier; does anyone on this
list know how Subversion WebDAV properties work, or know of some
documentation I could go to in order to find out? (There's always the
source code, I suppose...)
The interesting question, however, is why Subversion would throw away
all XML namespace information, rendering it incompatible with WebDAV at
the most fundamental property level. There seems to be no technical
reason for this---if Subversion wanted to set custom properties, it
could do so using its own namespace. And if Subversion had problems
versioning properties from other namespaces, it could encode them and
treat all properties as non-namespace opaque strings behind the scenes,
yet unencode them and give them back in their correct namespaces.
Why was the design decision made to break WebDAV support? Where can I go
to find out?
Thanks,
Garret
