the storage, where the sub element should be searched.
@param sSubElement
the full name of the sub element.
e.g. "default.xml"
@param eOpenMode
a flag field, which set the open mode for this operation.
@param bAllowFallback
if eOpenMode contains an ELEMENT_WRITE flag this parameter
allow to remove it and try it with the rest of eOpenMode flags
