You are completely right.
As I said, sometimes I just can't see the easy way to solve a doubt :)

Thank you very much,

There are no reserved words in XPath at all (which is an important
feature as it has to work with any XML: ENS in the above selects child
elements called ENS, there are no words "free".

In this case you dion't want an = test at all, a non empty node set
coerces to true, so you just need

<xsl:if test="not(Parent/MyNode)">...</xsl:if>
