I meant PPTX side, mainly various 'dictionaries'. When e.g. a new slide is
added, its ID is registered in the main file. The slide is derived from a
default template, which must be linked via its ID. Slides can have
annotations, there is also a special template for them, it has to be linked
to the slide as well, and so on...
This cross referencing in POI is out of the box. You just add a new slide
and all references are updated automatically. Yes, it is doable in pure
XSLT, but with additional effort.
Another thing is bulding the final PPTX file.

I simply didn't know that.
Thanks for explanation,
