I have an XML doctype running in Epic 5.1. Every time a document is loaded, the following error is displayed:
Thanks guys! I have done a little more research and found that the reference to the acl file was in fact through a pubrc file created way back (2004). It was done in order to allow a custom Tools > Compose using the E3 menu. However, it has fallen out of use now.
I am running version 5.1 and do not have the launch_ui.acl file in the Arbortext folder so thanks for copying in the contents.
