Passing a JSON Pointer with a schema

I'm looking at using ajv-cli to help test Hyper-Schema requests and responses. This means that the schema I want to validate against is not always the entire schema file.

What would you think of allowing something like:

ajv validate -s "foo.json#/links/0/targetSchema" -d "data.json"
or with .json omitted:
ajv validate -s "foo#/links/0/targetSchema" -d "data"

It would, of course, not be too hard to write some other script to pull out the appropriate schema, and that might be better given that selecting a link by numeric index is pretty fragile. So I'm not sure this is the best solution but thought I'd float it .
