How to ignore some composers

[simoncn]

"Not equals" isn't supported. The current "@tagname=value" tests can be implemented very efficiently by looking up each tagged "tagname=value" combination in a hash table constructed from all "@tagname=value" lines. This wouldn't be possible for a "not equals" test.

A list of values would need to be represented as multiple @ lines because there is no list separator character that can't be part of a tag value. This adds complexity and doesn't provide any more functionality than repeating the @ line (and its associated & - + = lines) for each value that you want to match.

I understand the desire for more flexibility in how tagged values are presented to the user when browsing the library. I am interested in exploring ways to provide this flexibility in a future version of MinimServer but it is unlikely that the solution will involve extensions to tagUpdate.
