The general stringparam author-tools may be set to yes to activate special handling of the <todo> element, the @provisional attribute of an <xref> element, and notation and index entries. The -specific stringparam latex.draft set to yes will automatically activate the previous features, in addition to a few others appropriate to the printed page. We have an XSL stylesheet that dumps every <todo> and every @provisional attribute to the screen as a simply-formatted text report, but it is not public now.
