[IDS] System Health extensions to the PWG MFD Model Schema

The PWG Semantic Model schema has been updated to include the System
Health related attributes.  Please take a look at the schema and let me
know if the modeling is in line with your intent.   Please send comments
to the IDS mail list.  I will make sure any comments and their
resolution are reflected in the MFD group.


 The entire PWG schema in a zip file can be downloaded at 



For your convenience and the convenience of those of you without
graphical schema tools the link below will be useful and a more direct
way to examine the power elements.


NOTE: when browsing the model at the MFD site click on the box with the
element name instead of the box containing the'+'.


The System Health extension to the System object's Status element can be
browsed at



The only comment I have at this time is related to style consistency.

The elements that have multiple instances (HealthFirmware,
HealthResidentApplication,  HealthUserApplication)  should have a
container object that is a single instance (i.e. HealthFirmwares,
HealthResidentApplications,  HealthUserApplications) that is a sequence
of the multiple instance elements.  This convention is used everyplace
else in the schema.  It also simplifies parsing for implementation that
have custom parsers.
