nsIMIMEInfo

Hello there!

Just wondering if it's possible to change the mime type of an opened file. I
have an XML document rendered with XSLT and I want to generate a XUL
document. Unfortunately XSLT can only generate XML so I was looking for a
way to change the mime-type of the generated file.

I've just seen nsIMIMEInfo and it's method SetFileExtensions, could it be
useful?

Any idea about it? I mean, any kind of idea!

Thanx, bye bye
