Problem w/ Defining Entities in Stylesheets

[JonTom Kittredge]

I just upgraded to Xalan 2.4.D1 and I am getting errors on my
stylesheets, which worked fine with previous versions.

The errors seem to be focused on the entity definitions we have at the
top of our stylesheets. For instance, if I try to run the following
stylesheet --

    <?xml version="1.0" encoding="utf-8"?>

    <!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#160;"> ]>

    <xsl:stylesheet version="1.0"
      xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

      <xsl:template match="/"/>

    </xsl:stylesheet>

-- I get the following errors --

    [Error] entity-test.xsl:6:52: Element type "xsl:stylesheet" must be 
declared.
    [Error] entity-test.xsl:8:28: Element type "xsl:template" must be declared.

    <?xml version="1.0" encoding="UTF-8"?>

If I have a more complicated stylesheet, every single xsl element is
reported as undeclared. If I remove the DOCTYPE declaration, then the
stylesheet parses without an error.

I believe that this DOCTYPE declaration is a perfectly XML
construction. Any hints on a fix this problem or another way to define
entities would be received gratefully. It would be a major hassle to
replace all uses of  "&nbsp;" with "&#160;", not just because we use
it in thousands of places, but because who can remember what character
160 is?

Thanks, JonTom
