Overview

A SourcePosAdapter describes a position relative to an origin. (Typically an OriginAdapter is associated with the root of a model. This origin has a URI to the resource, and a line number. The offset in the SourcePosAdapter is then relative to this origin. (This somewhat complex structure makes it possible to correctly refer to a source position in source that is embedded in some resource; a parser only sees the embedded snippet of source text and does not know where it was embedded).
