2.2.1 [W3C-PICS-Services] Semantics of the application/pics-service Description

V0004:

The specification states:

Values in PICS labels may be integers or fractions with no greater range or 
precision than that provided by IEEE single-precision floating point numbers. 
Values may be given names by using the label attribute. When a value is given a 
name, it may optionally have attached an icon and a human-readable description. The 
description for each category can specify restrictions on the range of permissible 
values for certain named attributes. Values may be restricted in a variety of ways:
 
1. minimum (min attribute, defaults to -INF) value; 

2. maximum (max attribute, defaults to +INF) value; 

3. integer values only (integer attribute, defaults to false if the attribute is 
omitted, but true if it is present with no value specified); 

4. named values only (label-only attribute, defaults to false if the attribute is 
omitted, but true if it is present with no value specified). 

5. more than a single rating allowed for a given document (consider the dimension 
"sizes available"). This is indicated by setting the attribute multivalue to true 
(default is false if the attribute is omitted, but true if it is present with no 
value specified). 

6. unordered values (unordered attribute, defaults to false if the attribute is 
omitted, but true if its is present with no value specified.)

All Document Modes (Internet Explorer 7)

Large integers or fractions as defined by IEEE single-precision floating-point numbers reference [IEEE754-2008] are not recognized or compared.

V0005:

The specification states:

In particular, the defaultable-options of a category (extension, integer, label-
only, max, min, multivalue, and unordered) are inherited by each category from its 
enclosing (parent) category.

A ratings file that is incorrectly constructed functions in the same manner as a correct ratings file.
