Valid IDs

[ioquatix]

Hello.

HTML5 allows any character to be an ID.

So:

# Thing {#Bake-Types-self.Any}

should be valid.

If we change this, I would make the ID XML-compatible so that the XML syntax of HTML5 is also supported - what do you think?

I think that's fine.

What's the implications of making it XML-compatible? I couldn't tell from the linked documentation. My understanding HTML5 basically allows any character. I assume except #?

[gettalong]

Yes, HTML5 allows any character. However, there is also an XML syntax version of HTML5 (formerly known as XHTML) which might have a problem with that (didn't find anything on that, though).

The XML syntax has a special ID type with certain allowed values. I have changed kramdown to allow all characters that are also allowed for this ID type. See https://www.w3.org/TR/xml/#id and https://www.w3.org/TR/xml/#NT-Name.
