Title: Message
I also support the usage of must in this case.
The question of fragments generated by the same Producer (= WSIA Web
Service) relates to the "harder" case where you need to place two services of
the same service on the same page (e.g., two stock quotes):
- The reason why this "harder" is because one can't assume a "static"
unique token (such as a namespace or a prefix) to ensure uniqueness.
- The need for this requirement is
clear; its importance is not completely obvious; there seems to be a strong
sentiment in this committee (including myself) that it's important enough to
consider.
How about the following: emphasizing that there could also be multiple
services, but also a single one:
This specification MUST provide a mechanism that ensures
that different presentation fragments (generated either by multiple WSIA
Web Services or
by a single one) can be "safely" combined to a
single document. In particular, if a presentation format
(such as HTML) mandates uniqueness of tokens in a single
document, it MUST be possible to compose a page in a way
that guarantees uniqueness.
