If the value of the attribute is a constant, as in the example, then
you can use document('') to get at it.  If its actually derived from
something else, then that method won't work (the xpath will give you
the XSL instructions defining the value, not the value itself).
Instead you can do this (where 'yes' could be replaced by some
expression: note the double quoting, select="yes" means something else
entirely).

   <xsl:variable name="display-value" select="'yes'" />
    <xsl:attribute-set name="set">
          <xsl:attribute name="display">
             <xsl:value-of select="$display-value" />
          </xsl:attribute>
     </xsl:attribute-set>

<xsl:template match="node">
       <xsl:if test="$display-value = 'yes'" >
                <!-- do something -->
       </xsl:if>
</xsl:template>

I don't *think* I'm falling foul of any XSLT rules - I haven't tested
this.
