Subject: [xsl] Usage scenarios of 'treat as' From: Frans Englich <frans.englich@xxxxxxxxx> Date: Mon, 29 Aug 2005 21:07:28 +0000 |
Hi, I'm curious on usage scenarios for the 'treat as' expression, in particular for when XSL-T 2.0 is the host language(if that matters). In XPath 2.0 is verification of an operand's type(the function conversion rules) done at runtime(implementation dependent if guaranteed runtime type errors are detected statically), unless the implementation implements "pessimistic" static type checking. (Right?) In what case is the 'treat as' expression useful, or required, when the implementation does not do pessimistic, static type checking? (that is, usage scenarios which applies for all implementations regardless of what optional features that are implemented.)
