Bug #2297
closed
Multiple comparisons in expressions wrongly allowed in XQuery syntax
100%
Description
Saxon allows multiple comparison operators in an expression (non-parenthesized), but this should not be allowed. e.g. See the failure of QT3 test op-boolean-equal-18: the expression 'true() eq true() eq true() eq true()' evaluates to true, but it should give a syntax error.

Another example is
10 to 10 to 11
which Saxon incorrectly accepts as valid, returning the result (10, 11).
Test case -s:op-to -t:rangeExpr-33 added.
