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>
