This means the name should be complete customisable by means of some 
user-provided rule. Currently, the <tag> feature can be used to specify a 
rule which returns the right name. If the rule prototype is:

rule tag-rule ( original-name * : original-suffix ? : target-type ? :
properties )
{

}

Then the rule can return new name using whatever rules, including those you 
list above. It will also be possible for one project to add version to lib 
names, and for another project to don't add it. What do you think?

The only question is how to conveniently specify in top-level Jamfile that 
specific <tag> feature should apply to lib targets.

I was thinking about

project top :
requirements <main-target-type>LIB:<tag>@some-naming-scheme
;

but this won't work for target which type is *derived* from "LIB", or if lib 
generator is used when building main target which type is not "lib".
