This code logs before the actual work gets done.  If an error is being 
masked, the log will be incorrect.

Property sheets aren't folder items.  You need a serializer that knows 
about the "propertysheets" attribute.  This code will only use the 
"propertysheets" serializer/gateway if the ZClass instance is folderish 
and has items in the folder.
