Expected Behavior

It is desirable to be able to control the heading weight -- sometimes bold is desired, other times a lighter weight is desired. The caller should be able to control that directly by weight (like text) and/or something that could be defined as a kind in theme (like Button theming) depending on level of flexibility desired.
