This extension adds support for the rel, rev and class attributes on external links:

• rel – The relationship of the linked URL as space-separated link types.
• rev – Specified a reverse link; the opposite of the rel attribute. Deprecated for being very confusing.
• class – A space-separated list of the classes of the element. Classes allows CSS and JavaScript to select and access specific elements.

Usage

The syntax is a little unorthodox. To set the rel attribute, place one or more tokens in double-parentheses at the end of the link title. e.g.:

  [http://tobyinkster.co.uk/ My website((me home))]

The above would be converted to the following link:

  <a href="http://tobyinkster.co.uk/" rel="me home" class="external">My website</a>

To set the class attribute, the same syntax is used, but tokens which represent classes are prefixed with a dot:

  [http://tobyinkster.co.uk/ My website((me .class1 home .class2))]

Becomes:

  <a href="http://tobyinkster.co.uk/" rel="me home" class="external class1 class2">My website</a>

Similarly, prefixing with a tilde (~) sets the rev attribute.

Tokens may be prefixed by a minus sign (-) to indicate that you don't want to add the token, but remove it. For example:

  [http://tobyinkster.co.uk/ My website((me -.external home))]

Becomes:

  <a href="http://tobyinkster.co.uk/" rel="me home">My website</a>

The "nofollow" rel token is considered untouchable though.
