NDATA is illegal type

    I've written some prolog so:

    <!DOCTYPE TEI.2 PUBLIC "-//TEI P4//DTD Main Document Type//EN" "some.dtd" [
    <!NOTATION PNG SYSTEM "http://www.w3.org/TR/REC-png">
    <!ENTITY some.png SYSTEM "some.png" NDATA PNG>]
    Trying to parse this with psgml, I always come up with

    Illegal entity type: NDATA

    However, nsgmls validates the file. I also notice that there are other problems with ENTITIES and psgml. Is this a bug?
