XML Parsing Error: undefined entity [OpenDocument Viewer beta2]

Solution: Try to use the OpenOffice.org (or another portable version) to open the *.ODT files couldn't open by the OpenDocument Viewer .

Log: After the ODT files generated by the GovForge service (in Chinese, 中文介紹), I tried to open the ODT files by OpenDocument Viewer version beta2. It showed the following message:

XML Parsing Error: undefined entity
Location: chrome://mozapps/content/downloads/unknownContentType.xul

The first ODT file in Chinese was not pass the ODF Validator test. It shows:

This file is not Valid OpenDocument 1.0!

1. error

in styles.xml
Expecting element style, got footer
Did not expect element footer there
Element master-page has extra content: footer
Extra element master-page in interleave
Element master-styles failed to validate content

Second ODT file in English is Valid OpenDocument 1.0

Both two files occurred the same errors!
