Actually, I'd rephrase that as:
When defined as "plain text", a WebDAV property *by definition* can't have
values outside the allowed XML character range. Where we (WebDAV server
developers) get in trouble is when in reality, the WebDAV server is just a
protocol adapter to some kind of back end system, which is NOT XML-based.
Inevitably, we'll have to find an escaping format which is XML 1.0
compliant, cheap and generally accepted. As this problem happens with
XML-RPC and SOAP as well, it would be nice to have a single, widely accepted
solution...
Some of the requirements are:
- the format of strings that *can* be represented as XML characters doesn't
change
- non-XML characters must be ignored by implementations not knowing the
escaping mechanism
