Correct identifier example type
Update profile example to use String type, rather than URI. This should address an issue that we're facing when creating profiles on top of this definition.
The error is: `StructureDefinition.snapshot.element[16].example.valueUri,message=URI values cannot have whitespace`
<type>
<code value="uri"/>
</type>
- <exampleUri value="http://www.acme.com/identifiers/patient or urn:ietf:rfc:3986 if the Identifier.value itself is a full uri"/>
+ <exampleString value="http://www.acme.com/identifiers/patient or urn:ietf:rfc:3986 if the Identifier.value itself is a full uri"/>
<isSummary value="true"/>
<mapping>
<identity value="v2"/>
<type>
<code value="uri"/>
</type>
