I am still struggling with the use of variables in some CREATE =
statements. The features do not always have the expected values after =
CREATE. Let me give another more concrete example:

TYPE pmcIdentifier;
BLOCK(ForEach) IdentifierAnnotation.propertyName=3D=3D"PMC"{} { // Just =
capturing scope
    IdentifierAnnotation.propertyName=3D=3D"PMC" { -> =
ASSIGN(pmcIdentifier, IdentifierAnnotation), LOG(pmcIdentifier.ct)};
}

TYPE doiIdentifier;
BLOCK(ForEach) IdentifierAnnotation.propertyName=3D=3D"DOI"{} { // Just =
capturing scope
    IdentifierAnnotation.propertyName=3D=3D"DOI" { -> =
ASSIGN(doiIdentifier, IdentifierAnnotation), LOG(doiIdentifier.ct)};
}

BLOCK(ForEach) XMLTagAnnotation.path=3D=3D"article/front/article-meta"{} =
{
    XMLTagAnnotation.name=3D=3D"article-meta" {
        -> CREATE(
            DocumentInfoAnnotation,
            =E2=80=9Cid" =3D pmcIdentifier,
            "doi" =3D doiIdentifier
        )
    };
}

The IdentifierAnnotation annotations have successfully been created in =
statements not shown here, which is also evident from a CAS inspection, =
and the LOG actions output the expected strings, but when I reference =
the variables in the CREATE action then the id and doi features of the =
DocumentInfoAnnotation end up pointing to the same identifier (pmc in =
the above example). Its puzzling me how this can happen.
