Yes it is.

Using +select you'd only have to add the xml one *once*.

And you'd do that in a resultset method so you'd only have to type -that-
once.

Please quit being combative and assuming things are harder than you think
they are, your problems are interesting but not -hard- to solve and while I'm
doing my best to help, your repeated default assumption that DBIC can't do
what you want rather than that you haven't been able to figure it out is
started to really piss me off - and that's not conducive to me wanting to
carry on helping you for free :P
