why cant i use:
exists() is an XPath 2 function, and xalan implements Xpath 1.
You don't need it though.
<xsl:if test="exists(/XPATH-QUERY)) = true">
That tests if the string value of the element <true/> is equal to "true"
which you probably don't want. The XPSLT test would be
<xsl:if test="exists(/XPATH-QUERY)">
which you can equivalently write as
<xsl:if test="/XPATH-QUERY">
Which would work also in an XSLT1 processor such as xalan.
