Just to explain why David Carlisle's solution works and yours doesn't, if
you use xsl:choose then you are creating a tree that contains copies of data
from the source node, you are not creating a node-set containing references
to the original nodes. So the general way of defining a node-set
conditionally is

<xsl:variable name="ns" select="$a[$condition] | $b[not($condition)]"/>
