SqlRuleAction is not sufficiently documented

[SeanFeldman]

Documentaiton doesn't provide sufficient information about what can be done with rule actions. The only documented functions are newid() and property(). And even these appear in remarks.

It should address questions such as

• What properties can it modify on what entities
• How to set values that are not string (datetime, boolean, numeric)

We have added this to the backlog, and will update this issue when we have more information.
