Sometimes documents are composed of different sections with different processing
rules (document + annexes, document + preamble or service pages, etc)

OO.o recognizes this need allowing to define different page numbering rules
(roman, arabic, etc) in page styles.

Unfortunately the same trick is not possible for outline numbering. You either
have to use different chapter styles for the special section (and they're not
recognized in TOC) or use the common outline styles asking manually to restart
numbering at section change (but you can't change the outline numbering style
from roman to arabic at this point)

I'd like to be able to associate a different outline chapter style set to
different page styles, with the option to restart chapter numbering at page
style change (ie either A B C 4 5 6 7 or A B C 1 2 3 4)
