Some examples
- Simple atomic feature attached directly to a locus:
<feat type="conceptIdentifier">ID67</feat>
- Basic feature whose value is a reference to a locus in the structural skeleton:
<feat type="partWhole" target="TE24"/>
- Basic feature anchored at the locus in the structural skeleton whose id attribute value is “TE24”:
<feat type="conceptIdentifier" source="TE24">ID67</feat>
- Compound feature anchored at “TE 23” and which makes reference to “TE 24”:
<feat type="partWhole" source="TE23" target=“TE24”/>
