Parsing error for StructureDefinitions with type slicing in R4B

[cybernop]

• fhir.resources version: 7.1.0
• Python version: 3.12.3
• Operating System: Ubuntu

Description

I was trying to read a structure definition that contains type slicing. The definition has the canonical http://fhir.de/StructureDefinition/observation-de-vitalsign.

What I Did

Then I tried to read the the resource from a JSON file

from fhir.resources.R4B.structuredefinition import StructureDefinition

file_path = pathlib.Path("profile.json")
StructureDefinition.parse_file(file_path)

which gave the errors

Expectation

It is expected to parse this definition correctly. The issue here is that a regex for id is used on Element.id which is an string and therefore does allow other symbols.
