Hi Folks,

I'm pulling my hair out over this one...

I've created a relatively simple DITA structural specialization, which
includes a (again simple) domain specialization. The specialization
package (shell dtd, .mod, .ent files) appear to be valid when tested
with oXygen 10.2.

I attempt to integrate the specialized DTD with XMetaL:

- In XMetaL, I choose Tools>Specialized DTD, select the base element
(topic), and specify a public ID. I close and restart XMetaL.

- I attempt to create a new document that conforms the specialized DTD.
File>New>Blank XML Document.

- I navigate to and select the specialized DTD in the XMetaL XAC folder.

XMetaL aborts the new document, with: "Error on line 2 of C:\Program
Files\XMetaL 5.5\Author\DITA\XACs\Foo\Foo_ditabase.dtd: A referenced
entity is already open."

I'm using XMetaL Author Enterprise 5.5 on Windows Vista. I've disabled
Vista UAC restrictions on the Program Files folder.

I would be grateful for any ideas about the possible cause of this
error. Thanks!

-Alan
