The count attribute must be a pattern, and "$element" is not a pattern.

It sounds as if $element is a variable that contains a pattern. In general
in XSLT you can't use variables to contain expressions, patterns, or parts
thereof, you can only use them to hold strings, numbers, node-sets, and
booleans.

You can probably use count="*[name()=$element]", if you're careful about
namespaces. <xsl:number> is the one place in XSLT where variables can be
used within a predicate that forms part of a pattern.
