Validation error (E Xerces)

[opa]

Hi I am pulling the following errors in my ditamap: "Attribute "id" is required and must be specified for element type "topicset"."
Any leads as to what I am doing wrong/how to fix?

Thanks in advance!
Olivier

Hi Olivier,

The <topicset> element is used to group topicrefs in order to conref them from other places.
So this is why according to the DITA specs, the ID attribute on a topicset is required:

https://docs.oasis-open.org/dita/v1.2/o ... icset.html

Looking at your sample DITA Map, you could probably use topicref instead of topicset.
