Support for conditional attributes?

See original GitHub issue

html`
  <div data-something-optional="${nullableValue}"></div>
`

It can be useful if we get a declarative HTML way to conditionally define an attribute. Thoughts?

<div data-something?="${nullableValue}"></div>
It’ll also avoid a rare but potential clash with having optional in attribute name.

? still is a valid attribute character.

document.createRange().createContextualFragment("<a what?='abc'>").children[0].getAttribute("what?")
// "abc"
