Plugin Naming for Extensions

[scottgonzalez]

Currently plugin suites reserve all names with their given prefix. Plugins that extend a plugin from a suite should be allowed to use the suite's prefix. The can be accomplished by allowing non-suites to use a suite's prefix if they contain at least one extra dot. For example, jquery.ui.autocomplete would be reserved for the jQuery UI suite, but jquery.ui.autocomplete.html would be available to anyone.
