XML and repeatable model groups

I've been trying to modify Jon Bosak's SHAKESPEARE dtd in order to make it
work with the newest version of NSGMLSU (ver. 1.1.4), that came with Jade 0.7.

Using this command:

d:\sgml\instans\shakespe>nsgmlsu -wxml -s hamlet.xml

>From the dtd: <!ELEMENT line     (#PCDATA | stagedir)*>

This is correct, so no errors are reported.

>From the dtd: <!ELEMENT line     (#PCDATA | stagedir)+>

D:\WINUTILS\JADE\NSGMLSU.EXE:shakspe2.dtd:22:39:W: #PCDATA in model group
that is not repeatable

Why is this flagged as an error/warning? Isn't this a repeatable model group?
Or isn't (#PCDATA | stagedir)+ a legal model group in XML?


>From the XML-draft (970331) section 3.2.2:

Mixed-content declaration[45] 

Mixed::= '(' S? %( %'#PCDATA' ( S? '|' S? %(%Name (S? '|' S? %Name)*) )* )
S? ')*' | '(' S? %('#PCDATA') S? ')' '*'?

The spec doesn't seem to allow '+' in a Mixed-content declaration. Is this
