The currently committed spec for 1089 says this in the RenderKit docs:
determine the correct markup element to host the data-
attribute(s). Let this element be dataHostingElement. This markup
element will always be the outer-most markup element corresponding
precisely to this component instance. If necessary, a <div> or a
<span> must be rendered to host the data- attribute(s), depending on
whether or not the component is, itself, block or inline in
nature. For each entry in the map, do the following.
If the key is a ValueExpression get its value and append it to the
literal string "data-", without the quotes. Otherwise get the string
value of the key and append it to the literal string "data-" without
the quotes. Let the result be dataAttributeName.
If the value is a ValueExpression get its value. Otherwise get the
string value of the entry's value. Let the result be
dataAttributeValue.
Render an attribute on dataHostingElement using
ResponseWriter.writeAttribute(). The name of the attribute is
dataAttributeName and the value of the attribute is
dataAttributeValue. Also pass dataAttributeName as the last argument
to ResponseWriter.writeAttribute().

I am forming a detailed reply to Andy's summary and will have it out by
tomorrow morning.
