 * attribute. It is restricted to a single contiguous range of integers; 
 * multiple non-overlapping ranges are not allowed. This gives the lower and 
 * upper bounds of the total sizes of print jobs in units of K octets (1024 
 * octets) that the printer will accept. 
 * <P>
 * <B>IPP Compatibility:</B> The JobKOctetsSupported attribute's canonical array 
 * form gives the lower and upper bound for the range of values to be included 
 * in an IPP "job-k-octets-supported" attribute. See class {@link 
 * javax.print.attribute.SetOfIntegerSyntax SetOfIntegerSyntax} for an 
 * explanation of canonical array form. The category name returned by 
 * <CODE>getName()</CODE> gives the IPP attribute name.
