Section 4.2.3.2 says:
The Unicode string MUST NOT begin with a combining mark or combiningcharacter (see The Unicode Standard, Section 2.11 [Unicode] for anexact definition).
It should say:
The Unicode string MUST NOT begin with a combining mark or combining character (as defined in The Unicode Standard, Section 3.6 [Unicode], definition D52).
Notes:
Section 2.11 of the Unicode Standard explains what combining characters are only in general terms. Section 3.6 contains the actual definition.
----- Verifier Notes -----
The actual fix is probably closer to changing "exact definition" to "explanation of combining characters," and leaving the reference alone. But discussion indicates that more clarification is probably good, and that clarification needs to be in the broader context of a document update.
