In our discussions we discussed this very item.  We resolved that "Static" 
is static in the scope of not changing operationally but could change in a 
configuration type event.  As an example, volume static information might 
change in response to a FORMAT MEDIUM operation.

Hi Curtis,
Is the intention of the element and volume static descriptors to be really 
static, i.e. the will never change, or will their contents be static the 
same way that inquiry data is static, i.e. it may change infrequently? 
I’ve looked through smc-3r15, and it looks to me like it doesn’t allow
any change in the static data.	For instance I didn’t see any references 
to establishing a unit attention condition if element or volume static 
data changed.
However I can wonder if some sort of on-the-fly reconfiguration of a 
library might not result in at least the element static information 
Just curious as, of course, I haven’t been in on the conversation in a 
number of years.
All the Best,
