The code executes the "if/then/else as I expected but produces the

select anything"

What is the proper way to test the value of "ancestor::Set/@domain" that
avoid this warning?
Thanks,

If the warning comes from that line, it comes from the bit that you have written as ... so it is hard to give explicit help.

If you go

<xsl:template match="@foo">
....  <xsl:value-of select="@bar"/>

then you will get that warning as a foo attribute can not have a bar attribute. What you usually mean is the bar attribute of the element of which the current node is an attribute so


<xsl:template match="@foo"> .... <xsl:value-of select="../@bar"/>

where the ../ gets you up off the foo attribute and on to the containing element, so that you can select the other attribute.
