Casing was mentioned by somebody in a different comment, so this text was added in an earlier round and should have been in the version you reviewed. I think it is a useful reminder of the case-sensitive nature of XML document parsing, but, like the issue you raised, really is already implicit in the fact that the specification is about defining an XML-based, schema-validated representation. The new text in response to your comment focuses on the schema. The number format is described in the schema via a pattern, as in: ## a single code point code-point = xsd:token { pattern = "[0-9A-F]{4,6}" } I believe that the existing language in the spec (where the effect of the pattern is described in words) together with the pattern in the schema is sufficient to make clear that "01" is not valid while "0001" is. The new text in section 4 serves the purpose to act as a general reminder that documents that fail the schema validation must be rejected. Like the casing issue, this reminder is intended to be helpful, but one can argue that it isn't strictly needed. A./
