A version is identified by its version string, which consists of
up to three different numbers. Each number is an integer whose
minimum value is 0 and maximum value is 9999. The version string
consists of the following:
Major, minor, and bug fix number for packages
Major and minor number for policies
Syntax version number for policy types
The versioning concept that is provided by PMAD does not support
branches. This means the version tree is actually only a list of
object versions ordered by the creation time and identified by the
version number.
The order of two versions is defined by the following rule.
Version 1 is greater than version 2 if ( version_1.major > version_2.major ) ||
( version_1.major == version_2.major && version_1.minor
> version_2.minor ) ||
( version_1.major == version_2.major && version_1.minor ==
version_2.minor && version_1.bugfix >
version_2.bugfix)
For historical reasons, there are methods that return or require
either a version string or the version numbers of the object. The
version string may or may not contain leading zeros. For example,
"1.0.0" is equal to "0001.0000.0000", and "23.11.12" is equal to
"0023.0011.0012".
If there are two policies with the same policy ID and version
number, the policy with more trailing '*' characters is treated as
the higher version.
