I've been meaning to ask- is there any plan to add special support for XML
features such as string escaping? It would be very useful, IMHO, to have
something analogous to the \Q feature in perl5 for escaping regexps, but
which would do XML-style and escaping.
I'm specifically interested

Not correct. The second case is the same as:
