Yes, that's what we've done naturally. For SOAP we've tested it in situations described by our customers (often EAI-style stuff). For broadcast we can reproduce a variety of situations to match varying needs.

Obviously! There's a reason why despite the fact that my box is littered with all sorts of fun binfoset tools I use XML almost exclusively ;) The idea is simply to make it possible for people to keep using all the XML Unicode text goodness even when a step in their workflow makes it impractical/impossible, *not*at*all* to compete with XML. I wish the pollution-and-doom mongerers would give more thought to that aspect. -- Robin Berjon <robin.berjon@e...> Research Engineer, Expway http://expway.fr/ 7FC0 6F5F D864 EFB8 08CE 8E74 58E6 D5DB 4889 2488
