I don't understand your use of span:std_docNumber for copyright year; canonically it should be span:date, and the Word span style would be stddocNumber and stdpublisher. If you're intending Word compatibility, please use those instead.

@opoudjis I've just copy-past this fragment from the current https://github.com/metanorma/metanorma-iso/blob/main/lib/metanorma/iso/boilerplate.adoc?plain=1:

[[boilerplate-year]]
© span:std_publisher[{{ agency }} ]span:std_docNumber[{{ docyear }}]

span:std_docNumber replaced by span:date.

I'm having difficulty working out why I marked it up that way, but it was wrong. Thank you!
