Subject: Extending subject schemes
Robert and I are trying to work the items that are in draft comments
in the 1.3 spec. We need help from the TC on the following draft
comment (enclosed in a table below) in the "Extending subject
schemes" topic: Extending subject schemes The <schemeref> element provides a mechanism for extending a subject scheme.

The values in the referenced subject-scheme map are merged with the values in the current subject-scheme map; the result is equivalent to specifying all of the values in a single subject scheme map.
For the two referenced example topics, see the following: Example: Extending a subject scheme https://td-demo.titaniasoftware.com/portals/ui/sample/viewer/5519e16ce4b016f565df9582/5519e185e4b016f565df9959/r/example-subjectScheme-extension Example: Extending a subject scheme upwards https://td-demo.titaniasoftware.com/portals/ui/sample/viewer/5519e16ce4b016f565df9582/5519e185e4b016f565df9959/r/example-subjectScheme-extension-upwards.dita We either need to add normative content, or consider removing the example topics (which were present in 1.2). I don't know whether anyone is using this aspect of subjectScheme ... --
