Since entire translation is supposed to be inside PO file, and *most*
PO file editting tools don't allow easy addition of new messages, can
you propose a way to do this? (I can imagine entire DTD subpart to be
changable, see below)
Note also that Serbian might require a full set of 7 separate
entities in extreme situations (when all declinations get used; in
practice it will be anywhere between 3 and 5), so it's a bit of pain
to keep track of them all (and it's hard to name them so they can
be easily and correctly used).

Yes, but that conflicts with the goal I mentioned earlier. We've got
one XML document split into several .xml files. We want that entire
document to be translated using *one* PO file, and later merged
back. If I let libxml2 replace entities automatically, DOM tree I
get would be as if it was all in one file, and I won't be able to
remerge them file at a time (since I modify in-memory DOM tree, and
simply let libxml2 serialize it later on, thus ensuring correctness).
As a side effect, I'd also lose source-file references as used in #:
comments. But this is not a big issue I guess.

It's very hard to determine the sort of text contained in the
entity. It can be anything from simple text, well-formed XML,
to non-well-formed XML. It's a pain. So, we'd probably need to
assume it's at least well-formed XML.

The simplest way to achieve this is to simply let translators add
DTD extensions they wish themselves. Eg. have something like:
#. Translators: define any other entities you wish to use here
msgid "<!ENTITY app "Bug Buddy">\n"
But that will defeat the purpose somewhat, since we'd still require
translators to be proficient with XML (apart from knowing that they
need close their tags; perhaps another PO file "tag" 'xml-format'
would be nice to be understood by msgfmt). Yet, it should scale well
to anything translators feel like doing with XML.
It also complicates the code, because SYSTEM (and perhaps some other)
entities would have to be treated separately: we don't want
translators to redefine all of it.

I'll do that a bit later.

This was the other way around: we have multiple XML files joined
together using SYSTEM entities. We want translations from single PO
file with translations to go into multiple XML files which don't have
DTD's and stuff. As said above, if I let parser expand all the
entities, I lose track of files (and I cannot do it for non-complete
XML files, since I have no place to define entities at all in them).
So, what would be the best for *translators*? Allow them to define
DTD themselves? The current behaviour is what seems most sane to me
in the sense that it works for everybody (every language), without
complicating it too much.
