The example Bundle "PCT-AEOB-Bundle-1" has a reference to an ExplanationOfBenefit resource (PCT-AOEB-1), but the fullUrl has an invalid value (http://example.org/fhir/Claim/PCT-GFE-Inst-Example-1). 

Error from the IG Publisher

Bundle.entry[0] (l16/c6)error -  The fullUrl 'http://example.org/fhir/Claim/PCT-GFE-Inst-Example-1' looks like a RESTful server URL, so it must end with the correct type and id (/ExplanationOfBenefit/PCT-AEOB-1)

Change the fullUrl to: http://example.org/fhir/ExplanationOfBenefit/PCT-AEOB-1
