The SUBSTR function currently just supports two parameters: the string and the starting index. This form is also supported in SPARQL, but there should be an additional form that takes a third parameter for the length, so that arbitrary can be returned.

The implementation of this is currently blocked by limitations of the logical data model, which cannot capture ternary function terms yet: #466.
