 <!-- CSSPrimitiveValue interface -->

   <descr>
     <p>
       The <code>CSSPrimitiveValue</code> interface represents a single
       <xspecref href="&css2;/syndata.html#values">CSS value</xspecref>. This
       interface may be used to determine the value of a specific style property
       currently set in a block or to set a specific style property explicitly
       within the block. An instance of this interface might be obtained from
       the <code>getPropertyCSSValue</code> method of the
       <code>CSSStyleDeclaration</code> interface. A
       <code>CSSPrimitiveValue</code> object only occurs in a context of a CSS
       property.
     </p>
     <p>
       Conversions are allowed between absolute values (from millimeters to
       centimeters, from degrees to radians, and so on) but not between relative
       values. (For example, a pixel value cannot be converted to a centimeter
       value.) Percentage values can't be converted since they are relative to
       the parent value (or another property value). There is one exception for
       color percentage values: since a color percentage value is relative to
       the range 0-255, a color percentage value can be converted to a number;
       (see also the <code>RGBColor</code> interface).
