YM <xsl:when test='something or other'>

And you need an end-tag for <xsl:when>.

>    </xsl:choose>

You could also use <xsl:if test="something else"> if you only wanted
to check one thing.

test and select both take select patterns.  Select patterns have a
context, usually the node matched by the match pattern in the current
template:

<xsl:template match="foo">
  <xsl:if test="bar">
    <xsl:text>This is used if foo has a child called bar.</xsl:text>
  </xsl:if>
</xsl:template>

In this example, the context for <xsl:if>'s select pattern is the foo
element matched by the template's match pattern.  It would not be true
if there existed a bar anywhere; it has to be relative to the current
node.

Match patterns succeed if they can be true from any context.  Once
upon a time, there were restrictions on match patterns; they were a
subset of select patterns.  But in the current draft, that restriction
was removed:

   [2] MatchExpr ::= SelectExpr

The lack of restriction has apparently made implementation more
difficult, and I have a feeling it may come back in some form, but I
can't be sure.
