XPath operator: boolean object <= object

Standard excerpt:

If both objects to be compared are node-sets, then the comparison will be true if and only if there is a node in the first node-set and a node in the second node-set such that the result of performing the comparison on the string-values of the two nodes is true. If one object to be compared is a node-set and the other is a number, then the comparison will be true if and only if there is a node in the node-set such that the result of performing the comparison on the number to be compared and on the result of converting the string-value of that node to a number using the number function is true. If one object to be compared is a node-set and the other is a string, then the comparison will be true if and only if there is a node in the node-set such that the result of performing the comparison on the string-value of the node and the other string is true. If one object to be compared is a node-set and the other is a boolean, then the comparison will be true if and only if the result of performing the comparison on the boolean and on the result of converting the node-set to a boolean using the boolean function is true.

When neither object to be compared is a node-set and the operator is <=, <, >= or >, then the objects are compared by converting both objects to numbers and comparing the numbers according to IEEE 754. The <= comparison will be true if and only if the first number is less than or equal to the second number.

NOTE: When an XPath expression occurs in an XML document, any < and <= operators must be quoted according to XML 1.0 rules by using, for example, &lt; and &lt;=. In the following example the value of the test attribute is an XPath expression: <xsl:if test="@value &lt; 10">...</xsl:if>
