HTMLPurifier_AttrDef_HTML_ContentEditable

Base class for all validating attribute definitions.

This family of classes forms the core for not only HTML attribute validation, but also any sort of string that needs to be validated or cleaned (which means CSS properties and composite definitions are defined here too). Besides defining (through code) what precisely makes the string valid, subclasses are also responsible for cleaning the code if possible.
