Question About DITA Topics Created Using Flare 5

At my DITAbug presentation on Wednesday night, I was asked whether DITA topics created in Flare by exporting Flare's native XHTML to DITA were well-formed or valid. This proved to be a fairly unusual question and it took several phone calls to track down the answer.

The answer, with one caveat, is that the DITA files should be valid per the OASIS DITA DTD. If they are not, there's a bug and the problem should be reported to MadCap. The caveat is that Flare 5 does not support specializations.
