com.volantis.mcs.protocols.DOMOutputBuffer
This class extends AbtsractOutputBuffer with the methods which need to be implemented by OutputBuffers which contain a DOM, or partial DOM.
When creating output elements, the CSS display value needs to be set correctly. There are three different types of elements we create:
1. Elements that map like for like with the input, e.g. a table on input maps to a table on output. In this case the value of display should be preserved from the input styles.
2. Elements that are created from the input but are not like for like, e.g table -> div, pane -> table. In this case the display should be overridden with a value that is appropriate for the output. For example pane -> table has display:block as input but should have display:table as output. Note that where possible this should match the input in meaning as far as is practical.
3. As structural necessity, e.g. does not map to an input element and so does not have any styles of its own and therefore has to inherit them from its parent, e.g. tr. In this case the display should be set properly on the output.
NOTE: This class uses Java's Character.isWhitespace(char) to determine if a character is a whitespace. The characters that Java defines to be whitespace are a superset of those that XML defines to be whitespace. However, if the extra characters considered to be Java whitespace are used in an XML document, the XML parser will already have complained about these characters being invalid.
