Implementing multi-seller payments with merchant-id and data-merchant-id.

[EricHurt]

What is the recommended method of handling multi-seller payments where passing data-merchant-id as an attribute is required?

For example, if I have multiple merchants I am accepting payment on behalf of, I need to include merchant-id=* in the query params (already covered by this library), and data-merchant-id="merchant-id-1,merchant-id-2,merchant-id-3" (not covered by this library.

How should I go about including the attribute on the script tag while maintaining the behavior of the component?
