To give a bit more direction on the implementation, the steps for the
parsing function should be roughly:

1) basic parsing: remove '<' and '>' and ends and split by '-'
2) group parts into the three groups while checking that they are
valid (not empty, etc.)
3) return the groups

Each step should give an informative message if an error is encountered.

The validity checking function could check that each group is valid,
e.g. no modifier appears more than once, no more than one type and one
detail appear, etc.

The canonization function could take that output and build a keysym from it.
