And this works the way you want to?

xsl:value-of will extract the string value of the result of evaluating the
expression <http://w3.org/TR/xslt#value-of>. In you case, the result is a
node-set. Extracting the string value of a node-set will retrieve the string
value of the first element in document order
<http://www.w3.org/TR/xpath#function-string>. Use e.g. xsl:for-each to go
throught the node-set bound to $bool, and there extract the value of the
current node.
