A single XML character is a ·character range· that identifies the set of characters containing only itself. All XML characters are valid character ranges, except as follows:

• The [, ], - and \ characters are not valid character ranges;
• The ^ character is only valid at the beginning of a ·positive character group· if it is part of a ·negative character group·
• The - character is a valid character range only at the beginning or end of a ·positive character group·.

Note: ↑The grammar for ·character range· as given above is ambiguous, but the second and third bullets above together remove the ambiguity.↑
