Eliot,
I propose that we should add your examples to several topics.
In the language reference:
"keydef" -- keydef.dita
In the architecture specification:
"Keyref (indirect addressing)" -- keyref.dita
"Use by reference" -- conref.dita
"DITA map elements" -- dita_spec_23_mapstruct.dita
Maybe also
"DITA map elements" -- dita_spec_23_mapstruct.dita
Possibly put one part of it under
"Example of a simple map that defines keys".
Does that seem excessive, that is, are cross references adequate to put the examples in one lang ref and one arch spec topic and for readers to be led there from the others?
How does this fit with your reorg of linking and addressing?
Here's a revision of the two examples:
ø¤º°`°º¤ø,¸¸,ø¤º°`°º¤ø,¸¸,ø¤º°`°º¤ø,¸
The following example illustrates use of a key reference in an empty
