valid_child_elements

This option has been replaced with the new valid_children as of 3.4.

This option gives you the ability to specify what elements are valid inside different parent elements. For example you may force that only thead,tbody,tfoot are valid within a table element. This option gives you a lot more control of the output XHTML and to ensure that it is more valid according to W3C specifications.
