+ <value type="NCName">dep</value>
+ <documentation xmlns="http://relaxng.org/ns/compatibility/annotations/1.0">'dep' is

+ <value type="NCName">const</value>
+ <documentation xmlns="http://relaxng.org/ns/compatibility/annotations/1.0">'const'

+ <documentation xmlns="http://relaxng.org/ns/compatibility/annotations/1.0">'cat' is
+ used for syntactic categories, as separate from pos; note that these sets need not
+ be disjoint (at the lexical level, they usually overlap), but the frontend prefers
+ to keep them separate. 'cat' will be found in the context of chunking or
+ hierarchical parsing and will characterise nodes; it may also be found in
+ dependency annotations, to indicate labels on nodes, as opposed to labels on arcs
+ (the latter are signalled by 'lbl')</documentation>
