Proper TinyMCE Elements: Only allow specific CSS rules

The TinyMCE valid_elements property allows valid_elements to define a whitelist of valid HTML elements and their attributes. You can only allow paragraphs and links:

 tinyMCE.init({ valid_elements: 'p,a[href]' });

However, the style attribute is a problem. This is necessary for some things, such as alignment, but if you enable it, then it may contain all sorts of undesirable CSS rules. Is there a way to restrict its contents to allow certain rules, for example:

 a[href|style=text-align,font-size,color]

There you go, there is an undocumented option called "valid_styles".

As far as I know, this is not possible in version 3.3.9.3. It may be available in version 3.4 because the verification implementation will be changed (declared by Mociecode).
