The Comparison Operators

Strictly speaking, the equal and not equal operators are also comparison operators. However, they don't involve relative evaluations of values, so they're often considered distinct from the set of inequality operators. Although all data types support equal and not equal examinations, there are some data types where inequality isn't easily defined.

XSL supports a complete set of inequality operators, as summarized in Table 17.2.
