This file should be written to the *temporary* directory, in the first
instance---all files for export should first be written there---and
registered as an included file. This would be something like:
string const fcssname = addName(temppath(), "docstyle.css");
Then
runparams.exportdata->addExportedFile(fcssname);
if it opens correctly (or, I guess, after it closes correctly).

If this fails we should probably fall back to writing it to the file header.

Similarly here: If this fails, fall back to what follows.

Otherwise, this looks good. And useful.
