           Summary: Static typing of external context item tests

The following tests all fail static type checking as they contain expressions
which expect something with type quantified ZeroOrOne, but are passed in a
child:: expression which can return more than elements.

For example, from externalcontextitem-5

for $var in $input-context1/works/employee[1]
return $var/xs:float(hours)


The other tests are similar. Could they be changed to exactly-one(hours).

Relavent tests are:

externalcontextitem-2
externalcontextitem-3
externalcontextitem-4
externalcontextitem-5
externalcontextitem-6
externalcontextitem-7
externalcontextitem-8
externalcontextitem-10
externalcontextitem-11
externalcontextitem-12
externalcontextitem-13
externalcontextitem-14
externalcontextitem-15
externalcontextitem-16
externalcontextitem-17
externalcontextitem-18
externalcontextitem-21
