Suggestion from the ISO meeting in Seattle

[Patrick Durusau <patrick@durusau.net>]

Greetings!

During the ISO discussions in Seattle last week the following suggestion 
was made for cases where the standard does not or cannot define precise 
behavior.

> From ISO 9075-1:2008 SQL/Framework:
>
> * *
>
> *7.2 Implementation-defined elements*
>
> Every part of ISO/IEC 9075 contains an Annex that lists every element 
> of SQL and its processing that is specified
>
> in that part, and is permitted to differ between SQL-implementations, 
> but is required to be specified by
>
> the implementor for each particular SQL-implementation.
>
> * *
>
> *7.3 Implementation-dependent elements*
>
> Every part of ISO/IEC 9075 contains an Annex that lists every element 
> of SQL and its processing that is mentioned,
>
> but not specified in that part, and is thus permitted to differ 
> between SQL-implementations, but is not

> SQL-implementation.
This came up in the context of discussions about corrections to ISO 
26300. Particularly areas where in retrospect we were not completely 
precise and to offer more precision now might create incompatibilities 
with existing implementations.

I think it is an interesting suggestion and one that could prove to be 
useful.

Hope everyone is having a great week!

Patrick
