+
+  - Current approach is to add a XclExpRecordBase::SaveXml() method, which
+    would be used to write the XML content (while Save() would continue
+    writing the BIFF format).
+  - Q: How do we get to the Save()/SaveXml() methods (e.g. the SST export code)
+    #0  XclExpSstImpl::Save (this=0x1b170b0, rStrm=@0x7fffd4d5c4a0)
+        at /home/jon/Development/OpenOffice.org/ooxml/sc/source/filter/excel/xecontent.cxx:224
+    #1  0x00007f68b7e46ff7 in XclExpSst::Save (this=0x1abc300, 
+        rStrm=@0x7fffd4d5c4a0)
+        at /home/jon/Development/OpenOffice.org/ooxml/sc/source/filter/excel/xecontent.cxx:351
+    #2  0x00007f68b7de5090 in XclExpRecordList<XclExpRecordBase>::Save (
+        this=0x1b2d168, rStrm=@0x7fffd4d5c4a0) at ../inc/xerecord.hxx:282
+    // as above, starting at frame 2
+
+  - Thus, to get to the SaveXml() method, we need to add a slew of WriteXml()
+    methods that will (eventually) invoke the SaveXml() methods.
+
+  - ZipStorage for XML handling and StorageRef (XStorage interface)
+		- To construct ZipStorage, need XMultiServiceFactory (!), and
+			XInputStream.
+		- Have an SvStream; need to wrap SvStream with XInputStream
+			- OInputStreamWrapper in <unotools/streamwrap.hxx>
+		- Where do I get XMultiServiceFactory?
+			- Lots of places -- just grep
+			- perhaps XmlFilterBase _does_ make sense here.
+				- Do it anyway.
+	- Looking into having XclExpXmlStream inherit from ZipFilterBase
+		- problem: exception during construction, because ZipStorage hates me:
+		#0  OStorageFactory::createInstanceWithArguments (this=0x10612a0,

+		...
+		- Actual problem: xfactory.cxx:274, the CheckPackageSignature_Impl() call.
+			- fails because the empty file has content (!), thus fails the "package
+				signature check" (which tries to ensure the file format is correct).
+		- Underlying file is an SvFileStream, created in
+			SfxMedium::GetOutStream().
+		- So why's CheckPackageSignature_Impl() fail?  Because
+			lcl_ExportExcel2007Xml() had the code:
+
+				tools::SvRef<SotStorage> xRootStrg = new SotStorage( pMedStrm, FALSE );
+
+			That is, it was creating an OLE Structured Storage document over the
+			SvStream, and then (later) used the *same* SvStream and passed it to
+			ZipStorage.  This caused ZipStorage to complain because OLESS data was
+			already present in the file, with a different file signature than what
+			ZipPackage was expecting (go figure).
