Section 4.3.7 says:

   Whenever an LGR depends on character properties from a given version
   of the Unicode Standard, the version number used in creating the LGR
   MUST be listed in the form x.y.z, where x, y, and z are positive
   decimal integers (see [Unicode-Versions]).

It should say:

   Whenever an LGR depends on character properties from a given version
   of the Unicode Standard, the version number used in creating the LGR
   MUST be listed in the form x.y.z, where x, y, and z are non-negative
   decimal integers (see [Unicode-Versions]).

Notes:

A zero needs to be allowed in the version numbering, as included in the example below. Zero is neither positive nor negative. "0, 1, 2, ..." are the "non-negative decimal integers". Positive decimal integers start at 1.

Thus for "6.3.0" to be a valid example, the constraint needs to be "non-negative" rather than "positive".
