AFAIK the single file format was once
introduced to provide easy XSLT support.
Unfortunately it was not taking serious as the round trip of ODF
documents between single file format and ZIP is broken.
A zipped ODF saved as single file and loaded as saved as zip back
is not guaranteed to produce the same info set of the original
zip.
For instance, embedded files other than images get usually lost,
in addition the single file gets invalid when multiple similar XML
IDs exist in the files and even similar named automatic styles
from content and styles XML will cause a problem.
IMHO we should either specifying the single format in a way that
it is 100% compatible, e.g.
a) like a specified generic mechanism to map any file into the
single stream
b) like a specified mapping of IDs (XML, style names) of various
files (e.g. with the file path+name as prefix) into the single
file
or dropping the whole thing.
I would tend to drop it, as I see only burden to the implementor,
even the ODF Toolkit does not implement it. But I can not see the
overall benefit for the ODF format.
There is no problem in using such a file format internally, if it
suits the needs (e.g. WebODF), but IMHO it is just a bad idea to
specify it as an ODF document exchange option.
PS: Even in XSLT it gets annoying as all images will be BASE64
encoded, parsed by the XML parser, causing time inefficiency and
often out-of-memory exception, instead references inside the ZIP
could be resolved using SAX EntityResolver oder URIResolver.

the single file XML
