Sounds good.

Yes, in some sense they are. We could extend the XML format, but it
currently reuses the <vertex> and <cell> tags for coordinates and
cell mappings which seems both convenient and natural:

    <higher_order_vertices size="9">
      <vertex index="0" x="0.0"  y="0.0"/>
      <vertex index="1" x="1.0"  y="0.0"/>
      <vertex index="2" x="0.0"  y="1.0"/>
      <vertex index="3" x="-1.0" y="0.0"/>
      <vertex index="4" x="0.6"  y="0.6"/>
      <vertex index="5" x="0.0"  y="0.5"/>
      <vertex index="6" x="0.5"  y="0.05"/>
      <vertex index="7" x="-0.5" y="0.5"/>
      <vertex index="8" x="-0.5" y="0.0"/>
    </higher_order_vertices>

    <higher_order_cells size="2" num_dof="6">
      <cell index="0" affine="true"  v0="3" v1="0" v2="2" v3="5" v4="7" v5="8"/>
      <cell index="1" affine="false" v0="0" v1="1" v2="2" v3="4" v4="5" v5="6"/>
    </higher_order_cells>
