Item qualifier

You can use the item (i) qualifier only for attributes. It causes PPS to treat the value following the qualifier as a set of items.

You must choose a character, such as a comma, to separate the items in a set. The item separator:

• is required
• must be the last character in a value that uses the item qualifier
• can be any character not used in the items

You may add or delete only one set item at a time. For example, to add items to a set:

[i]toolbox::hammer,
[i]toolbox::screwdriver,

To delete an item from a set, specify a minus sign:

[-i]toolbox::hammer,

The following examples show incorrect item syntax and aren't permitted:

[i]toolbox::hammer,screwdriver,
[-i]toolbox::hammer,screwdriver,

If you try to add an item more than once, PPS ignores the duplicate attempt. For example, if you write the following lines:

[i]toolbox::hammer,
[i]toolbox::hammer,
[i]toolbox::screwdriver,

a subscriber would read:

toolbox::hammer,screwdriver,

You can add null items to a set, like this:

[i]toolbox::,

A subscriber would read:

toolbox::hammer,screwdriver,,
