Description

The treat as operator code is testing type conformance, but not sequence cardinality, as illustrated by cbcl-treat-as-011 -

(1 to 10)[. mod 2 = 0] treat as xs:integer

which returns (2,4,6,8,10) incorrectly.

The problem is that the treat instruction only handles type checking. Under normal (Saxon EE) compilation the argument is surrounded by an appropriate cardinality check instruction if the cardinality is anything other than "*". This has now been added to the compile-XPath() code.
