Section 6 says:

In the case of an IPv4 prefix, the IPv4 address field is right-padded
with zeros up to 32 bits.  The PSID is left-padded with zeros to
create a 16-bit field.  For an IPv4 prefix or a complete IPv4
address, the PSID field is zero.

It should say:

In the case of an IPv4 prefix, the IPv4 address field is right-padded
with zeros up to 32 bits.  The PSID is left-padded with zeros to
create a 16-bit field.  For an IPv4 prefix the PSID field is zero.

Notes:

When there is a complete IPv4 address, the PSID field should contain the PSID. This is shown in Appendix A, Example 1. It shows an End-user IPv6 prefix and BMR that result in a complete IPv4 address. The resulting "IPv6 address of MAP CE" includes the PSID value in the the IPv6 Interface Identifier field.
