letters, digits, periods, and hyphens as names (of tags or
attributes). However, this broke too many pages which used
proprietary or strange attributes, e.g. <img src="a.gif"
v:shapes="whatever">.
So now we allow any character except:
* whitespace
* 8-bit and control chars
* characters that clearly cannot be part of name:
'=', '>', '/'.
This only affects attribute and tag names; attribute values allow
an even greater variety of characters. */
