Comparison expressions

Start of change Comparison expressions compare two values. XQuery provides general comparisons, value comparisons, and node comparisons. End of change

Value comparisons
Value comparisons compare two atomic values. The value comparison operators include eq, ne, lt, le, gt, and ge.
General comparisons in XQuery
General comparisons compare two sequences of any length to determine if a comparison is true for at least one item in both sequences. The general comparison operators include =, !=, <, <=, >, and >=.
Node comparisons
Node comparisons compare two nodes. Nodes can be compared to determine if they share the same identity or if one node precedes or follows another node in document order.
