phy:Property 

Property allows for typed and referenced properties from external
resources to be attached to 'Phylogeny', 'Clade', and 'Annotation'. The value of a
property is its mixed (free text) content. Attribute 'datatype' indicates the type of a
property and is limited to xsd-datatypes (e.g. 'xsd:string', 'xsd:boolean',
'xsd:integer', 'xsd:decimal', 'xsd:float', 'xsd:double', 'xsd:date', 'xsd:anyURI').
Attribute 'applies_to' indicates the item to which a property applies to (e.g. 'node'
for the parent node of a clade, 'parent_branch' for the parent branch of a clade).
Attribute 'id_ref' allows to attached a property specifically to one element (on the
xml-level). Optional attribute 'unit' is used to indicate the unit of the property. An
example: <property datatype="xsd:integer" ref="NOAA:depth" applies_to="clade"
unit="METRIC:m"> 200 </property>
