MARKLESS_ELEMENT_HANDLE_IDREF_COMPOSITE

One element() handle per IDREF attribute: a Markless compiler error.

Error from the compiler, while it builds your .tsrx files.

What happened

Markless prints the message, the reason, and a suggestion:

MARKLESS_ELEMENT_HANDLE_IDREF_COMPOSITE: One element() handle per IDREF attribute
The compiler resolves the relationship and the emitter mints the id. Combining handles would require the compiler to spell and order ids it cannot see, and id spelling is not something this record owns.
Reference one element() handle directly, as <attributeName>={handle}.
