/* Notes:
* 1. The 'value' can be one of the following:
* - an integer or string
* - an XPath expression
* - raw XML, which may or not not include other XSLT statements.
*
* 2. Always set 'no_cdata_parse' to true when the value is raw XML.
*
* 3. Set 'xpath' to true if the value is an XPath expression. When this
* is true, the value will be placed in the 'select' attribute of the
* <xsl:variable> element rather than in a child node.
*
* 4. Set 'param' to true in order to create an <xsl:param> instead
* of an <xsl:variable>.
*
* A word to PHP coders: Do not let the term "variable" mislead you.
* XSLT variables are roughly equivalent to PHP constants rather
* than PHP variables; once the value has been set, it is immutable.
* Keeping this in mind may spare you from some confusion and
* frustration while working with XSLT.
