How can the "Modify Attributes - Link/Xref" dialog be configured to recognize custom tags in my content?
Background:
I'm using a Design Science DITA DTD that includes <equation> tags as a customization. If I want to insert an xref/href to an equation tag, the process is very painful. The default "Modify Attributes - Link/Xref" dialog does not seem to "see" these custom tags, even when Type="Any" and Show="AllElement"|"All Elements with IDs" (see example image).
As such, writers have manually type the entire relative DITA link path, with all of the correct associated IDs. This process is Bonkers!
I believe that all of my paths are set to point Arbortext to the correct DTDs, and I assumed that arbortext functionality should conform to the DTD, but that doesn't appear to be the case here. What am I missing?
