Art Botterell commented on EMERGENCY-8:
---------------------------------------

Um... why?  Not clear what this achieves that isn't already possible using the <resource> element.  An example use case would be helpful.

We ought to be careful about allowing folks to add stuff that isn't open under the CAP spec.  That way lie proprietary extensions and probably other IP shenanigans.

Functionally, I think, any implementer should be able to make use of a CAP message armed only with the CAP spec.  She or he may _choose_ to enforce a profile, but shouldn't be presented with CAP messages that aren't fully usable to the extent of their individual content without applying some third-party schema.

> Steve Hakusa: To add hierarchical data to CAP, allow XML extensions in the CAP schema through the following change to the .xsd: <any minOccurs="0" maxOccurs="unbounded" namespace="##other"    processContents="lax" />
>   a. Allow such XML extensions at the <info> level, and optionally at the <alert> level. Having extensions at the <info> level would be required in case the hierarchical data is language-specific.  Extensions at the <alert> level could cut down on redundancy in the case the data is related to all <info> blocks.
> Jacob Westfall: Add extensibility with <xs:any## other minOccurs="0"/>
