[oXygen-user] Add custom catalog to OT build

[Scott Prentice]

I've got a custom framework that includes an OT installation that 
provides our custom doctype files and custom plugins. Editing topics 
that use this custom doctype is handled without problems, and using 
transformation scenarios that are supported by the embedded OT also 
works fine. But, I'd like to use an OT target that lives in the default 
Oxygen OT installation. My Oxygen DITA settings still point to the 
"built-in" OT, so when I set up a transformation scenario for the Oxygen 
OT target, it starts to work, but fails when it can't find the custom DTD.

When I add a pointer from [OXYGEN]/org.dita.base/catalog-dita.xml that 
references my custom catalog, the build completes fine. BUT .. I don't 
want to modify the default Oxygen installation files.

Some thoughts ..

- I don't think there's a param that I can add to the transformation 
scenario to reference my custom catalog .. is there?

- I've tried adding my catalog in Settings > XML > XML Catalog .. but 
that didn't seem to have any affect.

Is there any way to add a custom catalog without editing the default 
Oxygen files?

Currently using Oxygen 25.1.

Thanks!
