Description

Right now the Dpath expression parser doesn't provide detailed information about where sub-expressions are within an overall expression.

Since expressions can be fairly large, finer granularity positions for diagnostic messaging would be a big improvement. Right now we can just say "this error occurred", and the position is just that of the entire expression.
