Issue Solved

Before this commit, ISA string (component) "xextname0p0" is handled as the extension Xextname without any version information.

However, this is not what "xextname0p0" meant (Xextname version 0.0) and the parser needs to be fixed.

This change makes able to handle version 0.0 and enable handling placeholder extensions (with actual version number) easily (without being handled as an unknown version).
