		/* Notes about the XSLT variables array:
		 * 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.
