Questions about placeholders in ThingModel

[fix-all]

hi,
due to different domain names in different environments, can I use placeholders to replace domain names in the 'tm:submodel' and 'tm:extends' href attributes?
Based on my testing, this is not allowed. The href I set looks like this:
"links": [
{
"href": "{{WOT_MODELS_URL}}/base_model-0.0.1.tm.jsonld",
"rel": "tm:extends",
"type": "application/tm+json"
}
]

I think the placeholders can only be used to derive a TD from a TM - that's also how I understood the WoT standard:

[fix-all]

Yes, I used custom placeholders for this.

Yes, they are not intended to be resolved in the TM, as far as I understand the standard.
Only when generating the TD from the TM.

But I guess that would make sense to resolve such globally configured placeholders. Feel free to open an issue, we would accept a PR providing this.
