Hi,

An interesting practice I've come across at a client's site is instead
of using . they use self:: instead...
So instead of:
<xsl:apply-templates select="." mode="other"/>
you have
<xsl:apply-templates select="self::elem" mode="other"/>
and instead of:
.//whatever
you have:
self::elem//whatever
While it seemed a little odd to start with, their argument of it helps
locate where you are (especially when . is far away from the match
pattern that's normally used to discover the current node) is
beginning to grow on me...
It also works to test whether the current node is actually an 'elem'
when you process it or traverse from it.
Since when it isn't, it is silently filtered out, this could be
regarded as either a feature or a bug. If this isn't desired as a
feature, it may be a bug (or a bug waiting to happen), or perhaps at
best gilding the lily.
But it might serve as a sideways incentive for maintenance
programmers to learn their XPath. :-)
Cheers,
Wendell
