I use document('') only to perform call-template by it's
name, through variable
<xsl:template name="ra:sayHello"
match="xsl:template[(_at_)name='ra:sayHello']">
<xsl:text>Hello!</xsl:text>
</xsl:template>
...
<xsl:variable name="n" select='ra:sayHello'/>
<xsl:apply-templates select="document('')/*/xsl:template[(_at_)name=$n]">
Is there in XSLT 2.0 any alternatives to this technique?
You're basically using the FXSL technique where you use an element as a
representative or surrogate for a named template or function, and then you
dynamically call a named template or function by applying templates to that
element. There is no need for the element in question to be an xsl:template
element in a stylesheet, it can be any element anywhere. Take a look at the
FXSL library to see how it is done there.
