Workflow or API calls:
When testing test user nancysmart in R4 Sandbox, we noticed this in the Patient resource:
{
"extension": \[
{
**"valueUrl": "+1(415)354-1780",**
"url": "[http://hl7.org/fhir/StructureDefinition/iso21090-TEL-address](http://hl7.org/fhir/StructureDefinition/iso21090-TEL-address)"
}
\],
"system": "phone",
"use": "mobile",
"rank": 2,
"id": "CI-PH-29906485-10",
"value": "+1 (415) 354-1780"
}
Based on https://build.fhir.org/extensibility.html, valueUrl should be in a url format.



The current valueUrl in the phone format 1(415)354-1780 is causing validation error on our end. Could you have your team review whether this should be changed to a url format?
