This is the first problem. You really can't have two different identifiers
for the same leaf.
In your original example you had the equivalent of:
application (x) .abc (1) .noOfMessages (1) at the OID .x.1.1
application (x) .xyz (1) .noOfMessages (2) at the OID .x.1.2
So you really have two separate variables, but the problem is that you
have two definitions for the OID branch .x.1. It could either be
'abc' or 'xyz'. You can't really do that. Although it looks OK when
you look at two seperate MIB files, a good compiler should complain
(I think) if you try to compile both files at the same time. Note that
if you compile them seperately, each invocation of the seperate
files won't know about the other, and therefore won't complain
about the conflict/ambiguity.
So it all depends on what you are really trying to accomplish...
Your original example has two variables. But in your next example,
you want to have the same variable at two different locations/leafs...
Is there a way to define a leaf node (which is noOfMessages) with more than

Now the problem comes in making the OBJECT's leaf unique too
The closest merge to your original request would be the following
abc OBJECT IDENTIFIER ::= { application 1 }
xyz OBJECT IDENTIFIER ::= { application 2 }
noOfMessages OBJECT-TYPE
SYNTAX INTEGER
MAX-ACCESS read-write
STATUS current
DESCRIPTION "Number of Messages Transfred." "
::= { abc 1 }
noOfMessages2 OBJECT-TYPE
SYNTAX INTEGER
MAX-ACCESS read-write
STATUS current
DESCRIPTION "Number of Messages Transfred." "
::= { abc 2 }
Here you end up with two variables each at unique leafs:
application (x) .abc (1) .noOfMessages (1) at the OID .x.1.1
application (x) abc (1) .noOfMessages2 (2) at the OID .x.1.2
But here you would loose the concept of the 'xyz' branch.
