correct behaviour for entities as system identifiers

The short story is:
The CellML ( http://www.cellml.org/ ) DTD, which makes use of the MathML
DTD, includes the following code:
1 <!ENTITY % use_mathml_dtd "IGNORE">
3 <!ENTITY % mathml-charent.module "IGNORE">
4 <!ENTITY % mathml_dtd_path "'MathML-20010221/mathml2.dtd'">
5 <!ENTITY % mathml_dtd PUBLIC "-//W3C//DTD MathML 2.0//EN"
The Xerces parser reckons that "The system identifier must begin with
either a single or double quote character" on line 6, which I take it
means that it regards the apostrophes in the mathml_dtd_path entity
as just plain characters. Is this the correct behaviour?
The long story is:
Michael Kay's Aelfred parser, XP 0.5, and SP 1.3 all let this one
through and behave as expected.
If it wasn't already obvious what I was trying to do, I would like
to be able to have an entity that I can use to set the path to the
MathML DTD in a particular document's internal subset, if different
from the one specified there.
