XML file considered "Unknown File Type"

Hi,

I have XML files that lack an XML declaration. Part of the import process, though, is an XSLT stylesheet that adds one through standard XSLT output (ie, omit-xml-declaration="no"). However, Frame still decides that it is an unknown file type and forces me to select "XML" in that dialog box.

When I run an XML file through the stylesheet manually (with another processor), I see the declaration added. Furthermore, the externally-transformed file imports without a hitch.

Any ideas why the declaration is not recognized when added by XSLT during the import process? More importantly, any ideas how to get around this?

Thanks,
Russ
