Finally I am putting the pieces together for mod_i18n. The one thing
that is missing is that it needs to talk to the language negotiation. I

Hi.
I have a module (mod_xml2) that exports several functions and another
one (mod_i18n) that uses them. So by now mod_xml2 has to be loaded
first. This is of course not desirable and I want to get rid of it. Are
there any other possibilities than to make all exported functions
optional?

You were pretty close. According to nicks book (bottom of p. 324),

It might make sense to send sax events as buckets up the filter chain.
Can a module implement an additional bucket type?

I am using request pool memory for buffering in filters, and this will
