Section 3.1 says:

Description:

When a property is multi-valued, INDEX can be used to indicate an ordering or sequence of the values.  INDEX values must be strictly positive.  Zero is not allowed.

It should say:

Description:

When a property is multi-valued, INDEX can be used to indicate an ordering or sequence of the values.  INDEX values must be strictly positive.  Zero is not allowed.

If an instance of a multi-valued property does not have an INDEX value, then it is included at the end of the ordered sequence, as if it had a very high INDEX value. 

Notes:

It is not clear how a list of properties should be sorted if some of them have INDEX parameters and others do not.  This errata submission proposes that properties without an INDEX parameter be pushed to the end of the sorted list, as if they had a very high INDEX value.

For example, the ordering of the following properties is very clear, since they all have INDEX parameters:

INTEREST;INDEX=3:art
INTEREST;INDEX=2:baseball
INTEREST;INDEX=4:music
INTEREST;INDEX=1:hockey

The above example would be sorted as follows:

INTEREST;INDEX=1:hockey
INTEREST;INDEX=2:baseball
INTEREST;INDEX=3:art
INTEREST;INDEX=4:music

However, the spec does not provide guidance on how to sort a list of properties if some properties have INDEX parameters and others do not.  This errata submission suggests that the properties missing the INDEX parameter be pushed to the end of the sorted list.  For example:

Unsorted:

INTEREST:art
INTEREST;INDEX=2:baseball
INTEREST:music
INTEREST;INDEX=1:hockey

Sorted:

INTEREST;INDEX=1:hockey
INTEREST;INDEX=2:baseball
INTEREST:art
INTEREST:music

...OR...

INTEREST;INDEX=1:hockey
INTEREST;INDEX=2:baseball
INTEREST:music
INTEREST:art
