> Well, what would you recommend here?
Strictly speaking, every sentence in every paragraph in an ISO/IEC
standard should be normative. Do not write non-normative things as part
of usual paragraphs.
Non-normative information should be described in notes or non-normative
annexes. Ambiguous words such as "similar" should only be used in such
locations.
In this case, just mention Dublin Core and stop there. Non-normative
information might be useful as long as they appear as notes. At present,
the text looks normative and is slightly different from Dublin Core
in disallowing sub-tags.
