Any standard techniques for doing this? If raw input is xml
(defined by given schema/dtd), and final output is to be html, what format
would you use for the intermediate stages? Define a new dtd?

How do you centralise language handling? For localization, I'm using a
template which just holds the phrase dictionaries. Then every time instead
of printing a literal phrase, I have to call a lookup function, which
makes everything rather unreadable. Is that a case for multiple stage
handling (ie. use one language as the 'base' language, generate output
using this language only, then pass to the next stage template which does
the lookups for other languages and nothing else?). Or is there another
way of separating out localization tasks?
