Including HTML markup in title

[Javier Guerrero García]

Is there an easy way to include HTML markup in the Title / Clear buttons? I can do that via the options / localization object, but it gets escaped and displayed as HTML text contents (usage: for instance, to make the "close" button look like an actual button and include a glyphicon, since as it is a table cell on a collapsed table, border and margin options are quite restricted).

Couldn't find a "templates" properties for doing so also.
