I have a problem which would be best solved by an element, analogous to <tbody>, which could optionally be used to explicitly group <dt> and <dd> elements.

One of my pages includes a list of events, which I would like to describe using microdata.  The details of each event are spread across a <dt> element and several <dd> elements.  No one element in the page includes all, and only, the details of a single event.

My first attempt to add microdata used the itemscope and itemtype attributes on the <dt> element, with an itemref attribute referencing the several <dd> elements.  Not only is this cumbersome, but Google seems to ignore itemref.

I now use <meta> elements, and an empty <a> element, in the <dt> element, for the microdata I want to present to Google.  This means that data is needlessly duplicated.

An alternative would be to use a separate <dl> element to enclose the details of each event, but this obfuscates the underlying structure.

The page in question is at
