"az network nsg rule create" command parameter "--source-asgs" does not support multiple ASGs

"az network nsg rule create" command parameter "--source-asgs" does not support multiple ASGs while it's name, help output and documentation advice otherwise:

1. https://docs.microsoft.com/en-us/cli/azure/network/nsg/rule?view=azure-cli-latest says:

"--source-asgs
Space-separated list of application security group names or IDs."

2. "az network nsg rule create" says:
...
usage: az network nsg rule create [-h] [--verbose] [--debug]
...
[--source-asgs SOURCE_ASGS [SOURCE_ASGS ...]]

In fact, if you provide two or more ASGs following error occurs:

"A security rule may have up to 1 Application Security Group in the source or destination fields. The requested configuration has 2 in the SourceApplicationSecurityGroups field."

Start by comparing the network NSG rule specification with the `az network nsg rule create` parameter behavior and the linked CLI documentation. Verify whether the service accepts multiple source ASGs and identify which specification or generated documentation disagrees. Done means the repository accurately reflects the supported cardinality and its documentation is consistent.
