net.sf.saxon.expr.ExpressionVisitor.typeCheck()
Type check an expression, via the ExpressionVisitor @param exp the expression to be typechecked @param contextItemType the static type of the context item for this expression @return the expression that results from type checking (this may be wrapped in expressions thatperform dynamic checking of the item type or cardinality, or that perform atomization or numeric promotion) @throws XPathException if static type checking fails, that is, if the expression cannot possiblydeliver a value of the required type
