Subject: [OASIS Issue Tracker] Updated: (SOAEERP-16) PR08-E8bQoS-Spec-cd03.pdf, Rating-Specification.pdf, BSLA-spec-cd03.pdf



     [ http://tools.oasis-open.org/issues/browse/SOAEERP-16?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

William Cox updated SOAEERP-16:
-------------------------------

    Proposal: 
This applies to all of the specs with the "any" extensibility element.

"any" should instead be a list of artifacts in all versions of the specifications. The elements of the list are name-value pairs, where the name is constrained. the value can be "any".

All "official and approved' extensions have EERP starting the name, e.g. EERP_extension1. No other implementation may use that reserved prefix for names of extensions. [addresses conformance]

As the specs evolve and elements are brought in, there will then be no name conflict.

>     * Suggestion: Please consider adding the following addition to all
>       items that read: "This is an extensibility mechanism to allow
>       additional attributes, based on schemas, to be added to the abbrvX
>       element in the future. _*Requesting new elements for future
>       versions of the specification should be considered before
>       developing possible dependencies upon attributes which may be
>       deprecated in favor of such future elements.*_ Unrecognized
>       attributes MAY cause a fault or be silently ignored." 
> WTC: This comment has several aspects. 
> (1) The management of new attributes in the extensibility mechanism has a request for specific text
> (2) The evolvability and management of the spec requires a mechanism ("requesting new elements..." needs management)
> (3) The conformance statements must say something about conforming behavior if an attribute that is not understood is receive (the commenter's suggestion is in the description above)
> (4) Note should be taken that an arbitrary "any" at the end of an object is a serious barrier to evolution; viz. W3C TAG notes over the past 5+ years.
