<caolan> michael_: hmm, possible the new anchoring code, a checkin by OD/FME would be a good sign

Duplicate XML properties getting emitted (somehow)
	  + 'presentation:' prefixed

xmloff/source/draw/sdpropls.cxx



_clearly_ we shouldn't be outputting: background-objects-visible="true" 
background-visible="true" from 2.0

1.1 output to 2.0's idea of 1.1 output:

   <office:automatic-styles>
     <style:style style:name="dp1" style:family="drawing-page">
-      <style:properties presentation:display-footer="visible"
+      <style:properties presentation:display-footer="true"
-	presentation:display-page-number="hidden"
+	presentation:display-page-number="false"
-	presentation:display-date-time="visible"
+	presentation:display-date-time="true"
	transition-type="semi-automatic"
	transition-style="vertical-lines" transition-speed="fast"
	background-objects-visible="true" background-visible="true"
+	presentation:background-visible="true"
+	presentation:background-objects-visible="true"
	smil:type="randomBarWipe" smil:subtype="vertical"/>
     </style:style>

Some substantial changes - and (worse) painful duplication.

filters/source/config/fragments/filters:

writer8.xcu - new format:
	<node oor:name="writer8" oor:op="replace">
		<prop oor:name="FileFormatVersion"><value>6800</value></prop>
		<prop oor:name="Type"><value>writer8</value></prop>
		<prop oor:name="UIName">
			<value xml:lang="en-US">OpenDocument Text</value>
		</prop>
		<prop oor:name="Flags"><value>IMPORT EXPORT TEMPLATE OWN DEFAULT PREFERRED</value></prop>
	</node>
vs.
StarOffice_XML__Writer_.xcu - old format
	<node oor:name="StarOffice XML (Writer)" oor:op="replace" oor:finalized="true" oor:mandatory="true">
		<prop oor:name="FileFormatVersion"><value>6200</value></prop>
		<prop oor:name="Type"><value>writer_StarOffice_XML_Writer</value></prop>
		<prop oor:name="UIName">
			<value xml:lang="en-US">%productname% %formatversion% Text Document</value>
		</prop>
		<prop oor:name="Flags"><value>IMPORT EXPORT TEMPLATE OWN ALIEN PREFERRED</value></prop>
	</node>

The 'FilterService' is empty in both cases ...

It seems that xmloff/source/transform/* holds the key:
   OasisToOOo.cxx, OOo2Oasis.cxx etc.


We seem to have:

static XMLTransformerActionInit aStyleActionTable[] =
{

    And a set of macros to invoke different behaviors on various attributes.

Adding code to StyleOASISTContext.cxx
    XMLPropertiesTContext_Impl::StartElement()
	gives some helpful printout:

Attr name 'background-visible'
Attr name 'background-objects-visible'
Attr name 'presentation:background-visible'
Attr name 'presentation:background-objects-visible'
