[xsl] complex conditional statement

[Eric Smith <Eric dot Smith at fruitcom dot com>]

well complex for my level of XSL anyhow ...

This seems to work for me:
  <xsl:template match="section">
<xsl:if test=" $output='retail' and @retail='1' or $output='full' ">

Now I want to do this:
   <xsl:if test=" ($output='retail' and @retail='1') or $output='full' or ( $output = 'sale' and section[ancestor::sale])">

condition is true if the variable $output is 'sale' and the current
node - I explicitly named it here but because of the match statement in the line above, this need not be -
has an ancestor called 'sale'

I give up experimenting, ... please suggest correct syntax

thanx

( PS: I threw the parens in - not sure of that plays a role in xpath)
