Ah, i remember now, enum already supports this but the string parameter:
"must match exactly an identifier used to declare an enum
constant in this type."
which is, unfortunately, not what you want. The only other way i can
think of is to create a wrapper class that takes a string constructor
and from a method on the class the enum can be obtained.

I was wondering if you could combine a request entity with WebDAV
headers. Since my knowledge of WebDAV is limited the following might
not be suitable: for example:
@PROPFIND
public .. . put(PropFind find) {
}
the class PropFind encapsulates the request entity (if any) and
relevant WebDAV headers. The message body reader for the PropFind
would be responsible for reading the request entity and processing the
WebDAV headers. The above approach, if possible, might be easier for
the end user.
