It appears to me to be unspecified what characters are _allowed_ for attribute
names. Is it the ASCII [0-9a-zA-Z] as for tag names, or a specific set of
Unicode character classes, or any Unicode character at all?

Any unicode character except for space, tab, LF, FF, CR. NULL, ", ', >, /, =, or control characters.
