22. Specifying the type of counter created by list-style-type
	Chapter 4. Other extensions

A CSS rule such as:

ol[type="I"] {
    list-style-type: upper-roman;
}

implicitly creates a counter, but does not allow to give it a name or to parameterize it in any way.

Extension property list-item-counter may be used to specify the counter implicitly created by list-style-type. Example:

ol > li {
    list-item-counter: counter(list-item) ". ";
    counter-increment: list-item;
}

This property applies to elements having a list-item display.
This property is not inherited and cannot be inherited by specifying keyword inherit.
This value of property list-item-counter is similar to the value of property content, though it will almost always contain counter(), counters(), simple-counter() or simple-counters().
The default value of list-item-counter is: simple-counter(n, format), where format is implicitly specified by the value of property list-style-type.
