Hi Florent, Those errors appear when the DTD compatibility spec for ID/IDREF/IDREFs is enforced. By default that is enabled but you can turn it off in Options->Preferences -- XML / XML Parser -- Relax NG -- Check ID/IDREF. The link to the spec is here: http://www.oasis-open.org/committees/relax-ng/compatibility.html Basically one problem is that if some structure is matched by two patterns and one assigns a certain ID type then the other pattern should also assign that ID type. In general the issue appears when you have ID/IDREF(S) attributes defined by one pattern and a pattern that allows anything. The solution is to specify the pattern that allows anything to exclude the names that are defined as ID/IDREF(S). The other problem is I believe related with this part from the link above: *** # the first child of the element ancestor is a name element *** which disallows the use of the anyName or nsName name class in defining elements containing attributes with a not null ID type.

Hi,
I've downloaded the official XProc RNC grammar from:
http://www.w3.org/TR/xproc/schemas/xproc.rnc http://www.w3.org/TR/xproc/schemas/steps.rnc
When I open the main file (xproc.rnc) in oXygen, I get the following errors from oNVDL:
an "element" pattern containing an "attribute" pattern with a non-null ID-type must have a name class that contains only "choice" and "name" elements
conflicting ID-types for attribute "id" from namespace "http://www.w3.org/XML/1998/namespace" of element "catch" from namespace "http://www.w3.org/ns/xproc"
Before sending a defect report to the WG, I would like to be sure this is not because a restriction of oNVDL.
Best regards,
