I don't understand why the leading colon should be present.

In any case, it seems reasonable to:

- enclose attributes in braces (to indicate text meant for authors/editors rather than readers)
- append attributes to elements (where they are likely to be somewhat less hideous)
- use whitespace before the attribute lists for block elements (up to one blank line)
- use conventional syntax

	This paragraph has an attribute list attached by reference.

	{ref}

	[ref]: #id .class name=value

Am I missing something?
