Significance of "Identifier Value" in Data Stage E

[Sukanya2004]

Can somebody tell me what is the significance of the Number that follows the keyword "Identifier" in a Datastage Export File?
I have observed that for Job it is "V0"
For Stages it is a 4 Lettered Word like "V1S3" or "V0S4"
and for links 6 lettered words like "V1S3P1"
However I am not sure what does the number signify. Is it alloted randomly? Or does it have any significance? Also I have observed V0 follows the keyword "Container" . Does this only signify "Job" or anything else can be named with a two letter word like "V0" or "V1"?

V = view. The basic top-level design of a job is always V0. A local container is V1, the next local container added to the job is V2, and so on.

S = stage. The numeric part is the order in which the stage was added to the job.

P = pin. A pin is the intersection between a link and a stage. Again the numeric portion is the order that the link was added.

A = annotation.

So V1S3 is a stage in a local container. V0S4 is a stage in the basic top-level job design canvas. V1S3P1 is the first link that was attached to the stage represented by V1S3.

There are two reasons for this internal notation. The first is that it is compact. The other is that it allows jobs, stages and links to be named in local language (that is, the name property is just text, and can be Korean, Japanese, Chinese, etc.) but the underlying design is unaffected by the local language used.
