Description

This Zip package contains an extract of a META-INF/documentsignature.xml file.

1. In the only known-to-me established implementation of ODF 1.2 package signatures, a bug in how URIs of the form "#fragment" should fail, since the correct URI is "#META-INF/documentsignature.xml#fragment"

2. Demonstration that the references to resources that are part of the signed material are always references to the extracted file streams and not the compressed (or encrypted) Zip content. In particular, the references to fragments could not possibly be usable in that case, including cross-references in package file META-INF/documentsignature.xml itself.
