There weren't any objections, but I'm not convinced that the new type
will be an improvement over the fix checked in, so I'm going to mark
this issue resolved unless someone wants to raise an argument.

My vote would be for 2) Create a DependencyTreeHead which would make it

Since there is already a temp fix, we can wait and see if there are any
objections with adding this type first?

Subject: srl bug with one word sentences
I filed a jira (https://issues.apache.org/jira/browse/CTAKES-184) for an
issue in the srl component of the dependency parser. Here is the issue:
The SRL component grabs the Dependency Node for each token using the
token span. When there is a one-word sentence there are two such nodes,
the "head" node which spans the sentence and the token node. There is a
quick fix checked in that looks at the "id" field, but it would be
preferable to fix it upstream so that users of the Dependency types
don't need to know about this issue.
Here are a few possibilities, any other ideas?
1) Change the span of the head node, maybe to 0 length at the start of
the sentence?
2) Create a separate type for DependencyTreeHead, perhaps spanless
