[TxMt] Bundle snippets scope selector -- excluding scope?

hi,

i wonder if it's possible to "exclude" scopes using the "scope selector" setting for a snippet. for example:

the PHP bundle defines a tab-trigger for "array" that expands to $... = array ... thats fine as long as i am really in the scope "source.php". but when i am writing documentation (phpdoc -- which is in fact "source.php", too) it's really annoying when the 'array' keyword and such get's expanded.

i wonder what's the best solution to solve this ... would i have to define a scope "phpdoc" and overwrite the tab-triggers in there or is there any other solution?

thanks in advance,
