How deal with URI?

[sanpii]

Hello,

It’s easy to ignore URL (ie https://) from keywords but how can we (parser writers) should deal with the others URI like mailto:, tel:, etc.?

Don't include the URI?

Don't include the URI?

That's not a solution.

@sanpii Why do you want to ignore it? It's a valid key:value pair, just of an unusual nature. Personally I prefer to just accept protocols as commonly occurring key:value tags.
