RemovePredefinedTagSet: The Remove-AzTag cmdlet deletes predefined Azure tags and values from your subscription. To delete particular values from a predefined tag, use the Value parameter. By default, Remove-AzTag deletes the specified tag and all of its values.You cannot delete a tag or value that is currently applied to a resource or resource group. Before using Remove-AzTag, use the Tag parameter of the Set-AzResourceGroup cmdlet to delete the tag or values from the resource or resource group. The Azure Tags module that Remove-AzTag is part of can help you manage your predefined Azure tags. An Azure tag is a name-value pair that you can use to categorize your Azure resources and resource groups, such as by department or cost center, or to track notes or comments about the resources and groups. You can define and apply tags in a single step, but predefined tags let you establish standard, consistent, predictable names and values for the tags in your subscription.

RemoveByResourceIdParameterSet: The Remove-AzTag cmdlet with a ResourceId deletes the entire set of tags on a resource or subscription.
