                        throws PropertyException

      Return the default value.
      Overrides:
        `make` in class `PropertyMaker`
      Parameters:
        `propertyList` - The PropertyList object being built for this FO.
      Returns:
        the Property object corresponding to the parameters
      Throws:
        `PropertyException` - for invalid or inconsisten FO input

    - #### make

          public Property make(PropertyList propertyList,
                               String value,

                        throws PropertyException

      Create a Property object from an attribute specification. Check the value of the column-number property.
      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

    - #### convertProperty

          public Property convertProperty(Property p,
                                          PropertyList propertyList,
                                          FObj fo)
                                   throws PropertyException

      Return a Property object based on the passed Property object. This method is called if the Property object built by the parser isn't the right type for this property. It is overridden by subclasses. If the value is not positive, return a property whose value is the next column number.
      Overrides:
        `convertProperty` in class `PropertyMaker`
      Parameters:
        `p` - The Property object return by the expression parser
        `propertyList` - The PropertyList object being built for this FO.
        `fo` - The parent FO for the FO whose property is being made.
      Returns:
        A Property of the correct type or null if the parsed value can't be converted to the correct type.
      Throws:
        `PropertyException` - for invalid or inconsistent FO input
