Codex:

Removes all attributes, if none are allowed for this element.

If some are allowed it calls wp_kses_hair() to split them further, and then it builds up new HTML code from the data that kses_hair() returns. It also removes </code> and > characters, if there are any left. One more thing it does is to check if the tag has a closing XHTML slash, and if it does, it puts one in the returned code as well.
