Section Appendix A says:
Note that due to ambiguities in ISO 8601, some interpretations had to be made. First, ISO 8601 is not clear if mixtures of basic and extended format are permissible. This grammar permits mixtures.
It should say:
This grammar permits mixtures of basic and extended format.
ISO 8601:2000 section 5.4.2 reads:
d) the expression shall either be completely in basic format, in which case the minimum number of separators necessary for the required expression is used, or completely in extended format, in which case additional separators shall be used in accordance with 5.2 and 5.3.
