Resource Name

AWS::S3Tables::Namespace

Issue Description

According to CloudFormation doc for the resource type AWS::S3Tables::Namespace, the Ref is supposed to return the namespace name[1].

Ref
When you pass the logical ID of this resource to the intrinsic Ref function, Ref returns the namespace name.

However, it returns an ARN instead.

Expected Behavior

Return the namespace name. Or provide a GetAtt return.

Observed Behavior

It returns an ARN instead of the namespace name

Test Cases

As shown in the sample template, using Ref to retrieve the AWS::S3Tables::Namespace Namespace returns an ARN which is incorrect according to the CloudFormation Resource doc[1].

Resources:
  s3table:
    Type: AWS::S3Tables::Table
    Properties:
      Namespace: !Ref s3tablenamespace     -------> returns an ARN and not the namespace name
      OpenTableFormat: ICEBERG
      TableBucketARN: !GetAtt s3tablebucket.TableBucketARN
      TableName: mys3tablename
      WithoutMetadata: Yes

  s3tablebucket:
    Type: AWS::S3Tables::TableBucket
    Properties:
      TableBucketName: mys3tablebucket

  s3tablenamespace:
    Type: AWS::S3Tables::Namespace
    Properties:
      Namespace: mys3tablenamespace
      TableBucketARN: !GetAtt s3tablebucket.TableBucketARN

Other Details

As a workaround, we can use Select and Split to get the Namespace
Namespace: !Select [1, !Split ["|", !Ref s3tablenamespace]]
