Object
For every instance of a deltaValue object, one dynamic instance
entry is needed for holding the instance value from the previous
sample, i.e. to maintain state.
This object limits maximum number of dynamic instance entries
this system will support for wildcarded delta objects in
expressions. For a given delta expression, the number of
dynamic instances is the number of values that meet all criteria
to exist times the number of delta values in the expression.
A value of 0 indicates no preset limit, that is, the limit
is dynamic based on system operation and resources.
Unless explicitly resource limited, a system's value for
this object should be 0.
Changing this value will not eliminate or inhibit existing delta
wildcard instance objects but will prevent the creation of more
such objects.
An attempt to allocate beyond the limit results in expErrorCode
being tooManyWildcardValues for that evaluation attempt.
