I have an ElementDefinition where a dataElement is composed of a choice between multiple profiles of the same resource. This is generated properly by the IG Publisher:

"type" : [

{ "[code|http://hl7.org/fhir/R4/datatypes.html#ElementDefinition%23ElementDefinition.type.code]" : "Claim", "[profile|http://hl7.org/fhir/R4/datatypes.html#ElementDefinition%23ElementDefinition.type.profile]" : [ "[http://hl7.org/fhir/us/davinci-pas/StructureDefinition/profile-claim]", "[http://hl7.org/fhir/us/davinci-pas/StructureDefinition/profile-claim-update]" ] }

,

{ "[code|http://hl7.org/fhir/R4/datatypes.html#ElementDefinition%23ElementDefinition.type.code]" : "ClaimResponse", "[profile|http://hl7.org/fhir/R4/datatypes.html#ElementDefinition%23ElementDefinition.type.profile]" : [ "[http://hl7.org/fhir/us/davinci-pas/StructureDefinition/profile-claimresponse]" ] }

],

But it does not render properly:

<td style="vertical-align: top; text-align : left; background-color: white; border: 0px #F0F0F0 solid; padding:0px 4px 0px 4px" class="hierarchy"><a href="profile-claim.html" title="Claim">PAS Claim</a>, <a href="profile-claimresponse.html" title="ClaimResponse">PAS ClaimResponse</a></td>
