(In reply to comment #0)
Do you have a plug-in installed or in your workspace which provides the DTD? (see http://wiki.eclipse.org/Vex/UserGuide#Vex_Plug-in_Project:_Configure_your_own_XML_format)

Vex can only open files if their DTD is configured, either by an installed plug-in that extends the extension point 'org.eclipse.wst.xml.vex.ui.doctypes', or by a Vex plug-in project in your workspace. The plug-ins 'org.eclipse.wst.xml.vex.dita' and 'org.eclipse.wst.xml.vex.doctbook' are examples for plug-ins that provide the configuration for a document type.

I guess I don't have any plugin for this file type and don't have time to write one. It told me to file a bug report so that's what I did. It seems like a less than helpful way for VEX to fail.

If a document is opened in Vex that has no document type declared or uses an unknown document type, Vex should display a special error message which describes this problem and gives a hint on possible solutions to the underlying problem:

1. add a doctype declaration to the document
2. configure the document type e.g. by creating a Vex Plug-in in your workspace
