    - #### Maker

          public Maker(int propId)

      Construct an instance of a Maker for the given property.
      Parameters:
        `propId` - The Constant ID of the property to be made.

  - ### Method Detail

    - #### make

          public Property make(PropertyList propertyList,
                               String value,
                               FObj fo)
                        throws PropertyException

      Create a Property object from an attribute specification. If only `background-position-horizontal` is specified, `background-position-vertical` is set to "50%".
      Overrides:
        `make` in class `PropertyMaker`
      Parameters:
        `propertyList` - The PropertyList object being built for this FO.
        `value` - The attribute value.
        `fo` - The parent FO for the FO whose property is being made.
      Returns:
        The initialized Property object.
      Throws:
        `PropertyException` - for invalid or inconsistent FO input

    - #### getPercentBase

          public PercentBase getPercentBase(PropertyList pl)

      This is used to handle properties specified as a percentage of some "base length", such as the content width of their containing box. Overridden by subclasses which allow percent specifications. See the documentation on properties.xsl for details. Returns a `PercentBase` whose `getDimension()` returns 1.
      Overrides:
        `getPercentBase` in class `PropertyMaker`
      Parameters:
        `pl` - the PropertyList containing the property. (TODO: explain what this is used for, or remove it from the signature.)
      Returns:
        an object implementing the PercentBase interface.
