I have implemented FHIRPath Patch on top of the .NET FHIR API. I have used the tests provided as download in the specification as unittests. The "Quoted Names" refer to the names of those tests.

1. "Full Resource": would have expected valueXhtml for the new div instead of valueString. Now with valueString the actual types of the input div and the replacement div are different (xhtml vs string). But valueXhtml is not accepted, at least not by the .NET API.

2. "Add Anonymous type": structure with nested parts feels clumsy and was very hard to get parsed correctly. No other way?

3. What happens if sequential patches interact?

   1. For Delete:
      • array [0,1,2,3,4]

• delete array[0]

Trying to answer FHIR-I tracker items 13224, 13339 and 13348 the working group suggested to outline all possible combinations and work out their meaning.

The general rules we came to during the Mon Q2 session at WGM Jan 2018 were:

1. An element with a default value is considered to have that value if element is not present
2. An element without an element.value but with element.extension.count > 0 is NOT missing
3. An element with a default value is never a match for a search with modifier :missing=true, and IS a match for :missing=false
4. SUBSETTED and REDACTED tags:

• SUBSETTED meaning: Elements have been withheld from the response in accordance with the clients request.
