The JSON Bundles for the FHIR STU3 Definitions (linked at http://hl7.org/fhir/STU3/definitions.json.zip) contain some Strings that are incorrectly encoded using XML encoding. Specifically, there are two files, profiles-resources.json (2 lines affected) and dataelements.json (1 line affected), that include the sequence "#39;." instead of a single quote character "'". For example, on line 237524 of profiles-resources.json:

"expression": "(%resource.kind = #39;.logical#39;. or element.first().path = %resource.type) and element.tail().all(path.startsWith(%resource.snapshot.element.first().path&'.'))",

This is very problematic for loading these files into tools.
