      Bind property values from the property list to the FO node. Must be overridden in all FObj subclasses that have properties applying to it.
      Overrides:

    - #### validateChildNode

          protected void validateChildNode(Locator loc,
                                           String nsURI,
                                           String localName)
                                    throws ValidationException

      Checks to make sure, during SAX processing of input document, that the incoming node is valid for this (parent) node (e.g., checking to see that `fo:table` is not an immediate child of `fo:root`) called from `FOTreeBuilder.startElement(String, String, String, Attributes)` before constructing the child `FObj`.
      XSL Content Model: (#PCDATA|%inline;)*
      Additionally: "The content must not contain an fo:leader, fo:inline-container, fo:block-container, fo:float, fo:footnote, or fo:marker either as a direct child or as a descendant."
      Overrides:
        `validateChildNode` in class `FONode`
      Parameters:
        `loc` - location in the FO source file
        `nsURI` - namespace of incoming node
        `localName` - name of the incoming node (without namespace prefix)
      Throws:
        `ValidationException` - if incoming node not valid for parent

          public int getRuleStyle()

      Returns:
        the "rule-style" property

    - #### getRuleThickness

          public Length getRuleThickness()

      Returns:
        the "rule-thickness" property

    - #### getLeaderAlignment

          public int getLeaderAlignment()

      Returns:
        the "leader-alignment" property

    - #### getLeaderLength

          public LengthRangeProperty getLeaderLength()

      Returns:
        the "leader-length" property

    - #### getLeaderPattern

          public int getLeaderPattern()

      Returns:
        the "leader-pattern" property

    - #### getLeaderPatternWidth

          public Length getLeaderPatternWidth()

      Returns:
        the "leader-pattern-width" property

    - #### getAlignmentAdjust

          public Length getAlignmentAdjust()

      Returns:
        the "alignment-adjust" property

    - #### getAlignmentBaseline

          public int getAlignmentBaseline()

      Returns:
        the "alignment-baseline" property

    - #### getBaselineShift

          public Length getBaselineShift()

      Returns:
        the "baseline-shift" property

    - #### getDominantBaseline

          public int getDominantBaseline()

      Returns:
        the "dominant-baseline" property

    - #### getLocalName

          public String getLocalName()

      Returns the local name (i.e. without namespace prefix) of the node
      Specified by:
        `getLocalName` in class `FONode`
      Returns:
        the local name of this node

    - #### getNameId

          public int getNameId()

      Returns the `Constants` class integer value of this node
      Overrides:
        `getNameId` in class `FONode`
      Returns:
        `Constants.FO_LEADER`

    - #### startOfNode

          public void startOfNode()
                           throws FOPException

      Description copied from class: `FObj`
      Called after processNode() is called. Subclasses can do additional processing.
      Overrides:
        `startOfNode` in class `FObj`

      Description copied from class: `FObjMixed`
      Primarily used for making final content model validation checks and/or informing the `FOEventHandler` that the end of this FO has been reached. The default implementation simply calls `FONode.finalizeNode()`, without sending any event to the `FOEventHandler`.

      Note: the recommended way to override this method in subclasses is

      `super.endOfNode(); // invoke finalizeNode()`

      `getFOEventHandler().endXXX(); // send endOfNode() notification`

      Overrides:
        `endOfNode` in class `FObjMixed`
      Throws:
        `FOPException` - FOP Exception

    - #### collectDelimitedTextRanges

          protected Stack<DelimitedTextRange> collectDelimitedTextRanges(Stack<DelimitedTextRange> ranges,
                                                                         DelimitedTextRange currentRange)

      Description copied from class: `FONode`
      Collect the sequence of delimited text ranges, where each new range is pushed onto RANGES, where default implementation collects ranges of child nodes.
      Overrides:
        `collectDelimitedTextRanges` in class `FONode`
      Parameters:
        `ranges` - a stack of delimited text ranges
        `currentRange` - the current range or null (if none)
      Returns:
        the (possibly) updated stack of delimited text ranges
