* Flag used to determine what components of the version will be used

* An OSGi version has four parts as shown below:
* major.minor.micro.qualifer.
* It is not always desirable to use all four parts while
* exporting packages. In fact, maven version and OSGi version
* behave just opposite during version comparison as shown below:
* a maven version 1.2.3-SNAPSHOT is mapped to OSGi version 1.2.3.SNAPSHOT.
* In maven, 1.2.3 > 1.2.3-SNAPSHOT, but in OSGi, 1.2.3 < 1.2.3.SNAPSHOT.
* So, it is highly desirable to drop qualifier while computing the version.
* Instead of hardcoding the policy, we let user tell us what portions will
* be used in the OSGi version. If they ask us to drop minor, then only
* major will be used. Similarly, if they ask us to drop qualifier, then
* major, minor and micro portions will be used.
