Currently, if an attribute is created with a Unit of Measurement in an element template, it is not possible to change the Unit of Measurement in the element created from that template.
If no UoM is given in the template, then the UoM of the underlying PI Point is assigned.
It would be very useful if the UoM could be changed.
The same goes for Display Digits.
This allows for some relatively generic element templates (for example for assigning values, limits, texts, etc for use in a Collection in PI Vision).
I agree and would add Default Value and Value Type to the list.
I most care about Value Type as my points are mostly 0=Normal and 1=Alarm but occasionally inverted. Currently I am using 2 pi tags for this, the base tag fed from my EMSand then a second tag with an equation to invert it. It would be much simpler if I could go to the attribute and change the enumeration set.
