Unfortunately, subs_text doesn't seem to work across #PCDATA elements. What is the best way to coalesce them into a single element, within which subs_text should work? I can certainly concatenate the elements' pcdata() contents, but I'm wary of causing unintended consequences (say with character encodings, a topic on which I'm a little fuzzy), or missing some more elegant and robust solution already built into XML::Twig. Thoughts?
