The above uses an union expression, not an or expression. There's a difference.

  <xsl:if test="foo | bar">

collects two node-sets, creates an union and then casts the combined node-set to a boolean.

  <xsl:if test="foo or bar">

collects two node-sets, casts both of them into booleans and then makes an OR comparison between the resulting booleans.

The above should work, you might have stumbled on to a Xalan bug. 

Cheers,

Jarno
