Describe the problem

Hey, I just validated my SvelteKit website with https://validator.w3.org/nu/ and it heavily complained about sveltekit:prefetch not being valid HTML.

Is this a problem? Maybe if some service wanted to rank the quality of some website, they would use an HTML validator and adjust the ranking accordingly?

Describe the proposed solution

To avoid that, maybe the Svelte compiler could automatically turn such things into a valid HTML attribute like data-sveltekit="prefetch" from where the router can pick it up?

In my imagination this should be fairly easy to implement and would result in valid HTML.
