[DDI-SRG] Version Number Restriction

[J Gager]

All -
 
I have proposed the following restriction for version numbers:
 
    ([0-9])+(\.([a-zA-Z0-9])+)*
 
Basically you have to start a version with a number. After that you can have
"." seperated subversions which must be followed by at least one (but
possibly more) alpha numeric characters. No other characters are allowed.
 
For example
 
1 OK
1.0 OK
1.1A OK
1.1A.2 OK
1.1.1_A Invalid
1. Invalid
A.1.2 Invalid
 
Does anyone have an issue with this format? The idea is that we need a set
format so we can integrate it into the URN format. We want to make sure that
this doesn't conflict with any versioning schemes currently being used by
anyone.
 
Thanks,
 
J
