and we have already seen that this doesn't work perfectly in every case,
and won't work perfectly with generic heuristics, without the
pretty-printer applying ODF-specific rules.

let's take the first element from the list of <text:p> child elements
that don't currently do whitespace processing: <dr3d:scene> 10.5.2
it has a child <svg:title>, which allows <text/> content - so you want
to do whitespace processing there since it's a descendant of <text:p>.
however, <dr3d:scene> does not necessarily occur in a paragraph, it may
also occur in a <style:handout-master> element, which is never a
descendant of <text:p>.
do we now say that <svg:title> must have whitespace processing when it
occurrs as a descendant of <text:p>, but not otherwise? to me that is
the road to madness.
to me a necessary criterion to apply whitespace processing is that the
text content of the <text:p> descendant is conceptually part of the
paragraph text - so all captions on drawing objects and authors on
annotations and that sort of stuff shouldn't do whitespace processing.

"descendants" is better than "children", and furthermore i would perhaps
move all mention of "descendants" into non-normative notes, and leave
the normative text to say "processing shall be done if and only if the
element allows <text:s> etc. as children".

as said above i disagree with "any descendant".

i think we should restrict ourselves to specify something that has as
much backwards compatibility as possible with existing implementations,
with particular regard to how existing consumers will interpret
whitespace in ODF 1.3 documents.
given the current inconsistencies in implementations it's not possible
to make everybody happy, but we should not introduce additional
compatibility breakage that isn't there currently.
