Not if you're using a predicate, because position() inside a predicate is
different from position() outside the predicate.

As DC said, it's much better to make your variable hold the position as a
number rather than as a text node in a result tree fragment: that is, to use
the select attribute.

In fact there's an XSLT 2.0 solution that doesn't require a predicate and
therefore doesn't require a variable:

<xsl:value-of select="../../subsequence(colspec, position(), 1)/@colname"/>
