`LayerTag` documentation not consistent with `LayerTag` class

The documentation for `LayerTag` suggests that it takes arguments, however the class's `__init__()` does not support any arguments. What is the correct usage now?

Search the documentation and the LayerTag class for the existing usage example and __init__() definition. Confirm whether LayerTag is intended to accept arguments, then make the documentation consistent with the supported usage and verify that no argument-taking example remains.
