By using the @name attribute of the LOCATABLE classes as XML Element name we could create a more readable XML.
And collapse some of the DATA_VALUE_TYPES, e.g. the QUANTITY could just be written as "100 mmHg".
E.g.
<archetype_node_id>at0001</archetype_node_id>
tb:meaningsctid:246445000/tb:meaning
{3577F211-1D8C-4ce4-8579-D29DC083A96D}
English
<archetype_node_id>at0002</archetype_node_id>
tb:meaningsctid:271649006/tb:meaning
138 mmHg
