/**
 *  This list of WAI-defined roles are currently hardcoded.
 *  Eventually we will most likely be loading an RDF resource that contains this information
 *  Using RDF will also allow for role extensibility. See bug 280138.
 *
 *  Definition of nsRoleMapEntry and nsStateMapEntry contains comments explaining this table.
 *
 *  When no nsIAccessibleRole enum mapping exists for an ARIA role, the
 *  role will be exposed via the object attribute "xml-roles".
 *  In addition, in MSAA, the unmapped role will also be exposed as a BSTR string role.
 *
 *  There are no nsIAccessibleRole enums for the following landmark roles:
 *    banner, contentinfo, main, navigation, note, search, secondary, seealso, breadcrumbs
