I will provide the details in Version 10.   Additionally, I am working
with the architect to understand the need for 'statusbin' in their
upcoming features.

I will send all files with Version 10.   To aid in the review process,
I will keep all ..c in separate reviews.  It is less confusing that

What type of sample are you looking for.?   I can provide you with a
tree display of all attributes and some output samples for different
attribute types.
I will include sure-start  attributes, including current_value,
possible_values and the audit log properties.  Please let me know if
there is anything else you want to see.

Linux components are under development and not published yet.  The
only linux component at this time is the driver (hp bioscfg).
The only published components are under Windows ONLY.
