Re: Accessing attribute in a variable with conditional

Re:  Accessing attribute in a variable with conditional
The error you are getting at this line, <xsl:with-param
name="attribute" select="$validAttributeType/@base"/>

is because the variable "validAttributeType" is a result tree fragment
(it's a special data type defined in XSLT 1.0), and you are trying to
apply an XPath operation to it; which is not correct.

To my opinion, you need to use an extension function node-set for this
(if you are restricted to XSLT 1.0).

So for example, something like following will work:
<xsl:with-param name="attribute"
select="xx:node-set($validAttributeType)/xsd:restriction/@base"/>

(please bind the prefix xx to the required namespace - please see the
product documentation for this)

With XSLT 2.0, you will not get the error at all, for the operation
you are trying to do (because XSLT 2.0 implicitly treats the contents
of xsl:variable in this case as a node-set).
