Saxon XSLT and XQuery Processor

Using the key() function (or other functions that
depend on the context document, for example id(),
unparsed-entity-uri()) on the right hand side of the
"/" operator in a path expression causes a failure when
lazy evaluation of the expression is attempted. The
failure is:

java.lang.IllegalStateException: Expression still has
dependencies (64) after reduction
at
net.sf.saxon.expr.Expression.lazyEvaluate(Expression.java:152)

Lazy evaluation occurs in a number of situations, for
example when the expression is used in the xsl:result
of a stylesheet function.

Test case added: idky31

Source code fixed. The following change fixes this
problem, though it has not been fully regression tested.

At line 271 of net.sf.saxon.expr.PathExpression, change

(Dependency.XSLT_CONTEXT | Dependency.CONTEXT_DOCUMENT)

to

(Dependency.XSLT_CONTEXT)
