Some things I have tried:
<xsl:variable name="set" select="/a/b/c/*[((name() != 'y') and (name() 
!= 'z'))] | /a/b/c//y[1]" />

<xsl:variable name="set" select="/a/b/c/descendant::*[((name() != 'y') 
and (name() != 'z'))] | /a/b/c//y[1]" />

Then I tried to just exclude <z> at any level:
<xsl:variable name="set" select="/a/b/c/descendant::*[not(self::z)]" />
but that only excludes <z> elements that are children of <c>.

I'm using xsltproc, built with libxml 2.6.19 and libxslt 1.1.14
