An xsl:variable that contains a single xsl:value-of is almost always bad
coding. Use

<xsl:variable name="FOO" select="string(BehaviourInfo/Trap/Name)"/>

Apart from the fact that it's one line of code instead of three, it also
defines the variable as a string rather than as a tree. The only useful
thing you can do with this kind of tree in practice is to convert it to
a string, so it's much simpler and more efficient to create it as a
string in the first place.

I thought it worth mentioning because I'm seeing more and more examples
of this bad coding style.

Of course,

<xsl:variable name="FOO">
   <xsl:copy-of select="BehaviourInfo/Trap/Name"/>
</xsl:variable>

is even worse, and also very common.
