Subject: ucm: remove @@LibraryVersion and @@SyntaxVersion variables
X-Git-Tag: v1.2.14~15

ucm: remove @@LibraryVersion and @@SyntaxVersion variables

It seems that version checking is more complicated:

Syntax is one-way settlement from the configuration files.
It cannot be conditional.

The library version string is hard to check with regex.
