Hi,

please ask questions about Xtext in the eclipse.modeling.tmf newsgroup.
By default, you cannot edit files with an Xtext editor that are not
located in your workspace. Another limitation of the default
implementations is, that you cannot open files with the wrong file
extension with an Xtext editor.

Regards,
Sebastian
