A single ISO 10646 Character, e.g. "x"

Ref: *ISO 10646

The Character Attribute Type is used in the accesskey attributes of links and form controls as well as in the char attributes of table cells or groupings (although I do not know of any browser which supports the char attribute).

Handling Invalid Characters

If the character is

• a less-than character (<) it must be escaped as < (or <).
• an ampersand character (&) which does not denote the start of an entity or character reference (e.g. <) it must be escaped as & (or &).
• a double quote character (") it must be escaped as " (or ") if using double quotes to delimit the attribute value
• a single quote character (') it must be escaped as ' if using single quotes to delimit the attribute value (alternatively ' may be used if compatibility with HTML isn't necessary - see Character Entities Predefined by XML 1.0)
