not currently, and i wonder if it's intentional.

the string that is passed to doProofreading is pre-processed and doesn't
correspond 1:1 to the text in the paragraph, so you can't really know
where any given XTextRange is relative to that string, and not every
position in the string has a corresponding XTextRange...

the GrammarCheckingIterator iterator uses the SwXFlatParagraphIterator
to get the "dirty" paragraphs, and there doesn't appear to be any way to
get XTextRange for them.

on the other hand, there are XFlatParagraph methods like changeText and
changeAttributes that don't do this mapping, which looks like a bug?
these aren't used by the GrammarCheckingIterator, i wonder why they exist?

DDJ: You've mentioned Edsger Dijkstra. What do you think of his work?
DK:  His great strength is that he is uncompromising. It would make
     him physically ill to think of programming in C++.
