Consider the following scenario:
Changes could not be saved into the document.
The document is digitally signed. Remove the digital signature in a Microsoft SharePoint Foundation-compatible XML editor such as Microsoft InfoPath.

To work around this problem, do not select the "Include Content" option when you save the SharePoint site as a site template or as a solution package.
