--- Comment #3 from Nikolay Sivov bunglehead@gmail.com 2010-07-27 07:53:27 --- Yes, I think it's fine to send it: we can't skip DTD with libxml2 functionality, but if really happens to matter for some app we could pre-parse a stream and pass modified stream without DTD to libxml2.
For this case I think it's more like a precaution to skip DTDs, so S_OK is enough for a start.
About a FIXME I don't care too much will you put it inline or debugstr_w(), something like that (with value output) is enough:
"Ignoring property ProhibitDTD, value %d".
