The potential confusion here is that any reference to a "reliable Web
Service" may cause the reader to assume that this is reliable in the same
way as a reliable Messaging Service is reliable - and I don't think this is
what Hao intends at all...

>
> |   D-AC007.1 The Web Service Architecture is reliable.
> |
> |   D-AR007.1.1 The Web Service Architecture is precisely defined
> without

> |       D-AR007.1.1.1 using standard definition languages whenever
> |   applicable and available,
> |       D-AR007.1.1.2 using standard terms, and clearly defined new
> terms.

> It seems to me that reliable here is confusing: D-AR007.1.1 suggests
