Examples of client.net.sf.saxon.ce.expr.RoleLocator

client.net.sf.saxon.ce.expr.RoleLocator
A RoleLocator identifies the role in which an expression is used, for example as the third argument of the concat() function. This information is stored in an ItemChecker or CardinalityChecker so that good diagnostics can be achieved when run-time type errors are detected.
