I have read draft-ietf-entmib-state-01.txt and I generally like this
document. Below are some comments, many of them are editorial, others
ask for more discussion of relationships to other MIBs. But I also
understand that this can be done later when the document is revised.

a) Typo in section 2: "so this term us substituted".

b) Typo in section 2.1: "interesting issues not addresses in existing work"

c) Typo in section 2.2: "It also compare this combination of states"

d) state 'lock' for entStateAdmin of a container?

e) entStatAdmin is actually entStateAdmin

f) state 'active' for entStateUsage of a power supply?

g) state 'active' for entStateUsage of a fan?

h) Relationship of the entState* objects to the dot1dStpPortEnable of
   the BRIDGE-MIB?

i) Relationship of the entState* objects to the hrDeviceStatus of
   the HOST-RESOURCES-MIB?

j) Relationship of the entState* objects to the objects using the 
   SubUnitStatus TC of the Printer-MIB?

k) Is my understanding correct that alarmOutstanding(5) of the
   AlarmStatus TC is set when at least one of critical(2), major(3),
   minor(4), warning(6), indeterminate(7) is set? If not, the
   explanation can probably improved. ;-)

l) Implementation of the notifications is unconditionally optional?

m) In the security section, you may want to explain that access to the
   objects defined in this MIB allows to figure out what the active
   and standby resources in a network are and that this information
   can be used to optimize attacks on networks. So even read-only
   access to this MIB should be properly protected.

y) In general, the description of the states for each combination of
   entity class and state value is incomplete (see d,e,f above). What
   is the interpretation of combinations not mentioned in the text?
   Are such combinations simply undefined but not illegal or are they
   illegal?

Overall, I like this very much. A simple but highly useful addition
to the ENTITY-MIB.
