* make expand <code><time></code> and new date/time <code><input></code> elements to be consistentand reflect more real world use cases** handle the same set of year, month, date, time variants/subsets.** expand both time/input to handle additional real world cases*** YYYY*** YYYY-MM*** --MM-DD
* improve <code><time></code> element to support uses analogous to the "value class pattern" date and time separation use case (compose nested <code><time></code> elements into a single date and time)
** perhaps even use a <code><time></code> to compose multiple nested date/time <code><input></code> elements for specific date/time components into a single date and/or time.
