Properties passed to the proofreader could use some formatting information,
especially for:

(1) bulletted lines: they are spelled differently than standalone sentences in
some languages

(2) header lines: they are spelled specially, for example, in MS Word, there is
a special title-spelling rule that checks capitalization in titles

(3) italic portions: sometimes they are titles and should not be treated as
normal parts of the sentence (not used but just mentioned)

(4) end of line as seen on the page - some languages don't allow dangling short
prepositions at the end of the line (Czech, Polish, probably others), so these
should be entered with a hard space but it would be an overkill to add a space
to all possible prepositions; having some info about the end of line position
would be therefore nice

We get requests from users regarding these cases. Probably there should be some
very abstract formatting attributes used.
