Is the step p:xquery intentionally restricted to XQuery 1.0 and only returning document nodes?

[martin-honnen]

I have read through the spec and the issues and it seems there has been some intention to update XProc 3 based on XPath 3.1 and XSLT 3; however, the step for XQuery p:xquery in http://spec.xproc.org/master/head/steps/#c.xquery explicitly only names XQuery 1.0 in "The p:xquery step applies an [XQuery 1.0] query" and also restricts the result saying "The result of the p:xquery step must be a sequence of documents. It is a dynamic error (err:XC0057) if the sequence that results from evaluating the XQuery contains items other than documents and elements.".

Is that intentionally or is that step supposed to be updated along the further development of the specs to allow XQuery 3.1 and use of and return of XDM 3.1 sequences (in particular as the main spec in http://spec.xproc.org/master/head/xproc/#documents.9 mentions p:xquery as a potential step creating "new XDM instances")?

This is an oversight in the step description. Moving this issue to the step repo.
