  :type TransitGatewayRouteTableId: string
  :param TransitGatewayRouteTableId: **[REQUIRED]** 

    The ID of the transit gateway route table.

    

  
  :type PeeringAttachmentId: string
  :param PeeringAttachmentId: **[REQUIRED]** 

    The ID of the peering attachment.

    

  
  :type TagSpecifications: list
  :param TagSpecifications: 

    The tags specifications applied to the transit gateway route table announcement.

    

  
    - *(dict) --* 

      The tags to apply to a resource when the resource is being created. When you specify a tag, you must specify the resource type to tag, otherwise the request will fail.

       

      .. note::

        

        The ``Valid Values`` lists all the resource types that can be tagged. However, the action you're using might not support tagging all of these resource types. If you try to tag a resource type that is unsupported for the action you're using, you'll get an error.

        

      

    
      - **ResourceType** *(string) --* 

        The type of resource to tag on creation.

        

      
      - **Tags** *(list) --* 

        The tags to apply to the resource.

        

      
        - *(dict) --* 

          Describes a tag.

          

        
          - **Key** *(string) --* 

            The key of the tag.

             

            Constraints: Tag keys are case-sensitive and accept a maximum of 127 Unicode characters. May not begin with ``aws:``.

            

          
          - **Value** *(string) --* 

            The value of the tag.

             

            Constraints: Tag values are case-sensitive and accept a maximum of 256 Unicode characters.

            

          
        
    
    

  :type DryRun: boolean
  :param DryRun: 

    Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is ``DryRunOperation``. Otherwise, it is ``UnauthorizedOperation``.
