To see the difference, consider

But this is really the design I have:

<!DOCTYPE a [
<!ELEMENT a (x*) >
<!ELEMENT x EMPTY >
<!ATTLIST x
a CDATA "y" >
]>
<a>
<x a="n"/>
<x/>
</a>
Then ask for all the children of x that don't have an attribute that is 'y'
(or the different question, have an a attribute that is not 'y')
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:template match="a">
a: <xsl:value-of select="count(*[(_at_)a!='y'])"/>
b: <xsl:value-of select="count(*[not(@a='y')])"/>
c: <xsl:value-of select="count(*[string(@a)!='y'])"/>
</xsl:template>
</xsl:stylesheet>
$ saxon neq.xml neq.xsl
<?xml version="1.0" encoding="utf-8"?>
a: 1
b: 2
c: 2
So when I run this in Stylus or saxon I get the results that I expect:
a: 1
b: 1
c: 1
I agree this is an issue if the DTD did not exist, but it does and the
default values are there just like if they were typed in the data stream.
SO I don't see this as so much a warning against != as it is being aware of
the environment your processing in - unless I missed something.
