Description

When a query includes a declaration such as

declare context item as xs:integer external;

then the static type analysis of the query should be able to use this information.

Saxon is not doing so (largely because of the complications caused by the fact that different context item types can be declared in different modules).

There are no adverse symptoms, other than weaker diagnostics and missed opportunities for optimization.
