I would suggest making this optional, in case one only wanted to use <constraintDecl/> to declare a query language binding and nothing else.

I think you are quite right.
Good catch.
Hope to make change today.

Not just, BTW, in case user wants no <sch:ns>, but it would be appropriate to let poor user have 2 or more of them!

This won't do if we want to make this element only be used once, as #2330 required.

We only want 1 <constraintDecl> per scheme (rather than allowing multiples and using decarable/decaring mechanism), but we still have to allow multiples in case there is more than one scheme. E.g.
<constraintDecl scheme="schematron" queryBinding="xslt3"/>
<constraintDecl scheme="prolog">
$globalVarOne=FALSE;
$globalVarTwo=17;
</constraintDecl>(I have no idea if that is syntactically correct PROLOG; I kinda doubt it. But it does not matter for our purposes.)
That said, it might be a good idea to have a <constraintSpec> for <constraintDecl> that constrained use to only 1 per scheme. 😄

I would suggest interleaving a reference to an optional constraintDecl here.
<sequence preserveOrder="false">
<alternate minOccurs="1" maxOccurs="unbounded">
<classRef key="model.encodingDescPart"/>
<classRef key="model.pLike"/>
</alternate>
<elementRef key="constraintDecl" minOccurs="0" maxOccurs="1"/>
</sequence>
Added
<constraintDecl>element.
