solutionFormatVersion Attribute
Identifies the version number that represents the format of the form definition file (.xsf).
Type
xsf:xdSolutionVersion
Remarks
The solutionFormatVersion attribute is a required attribute of the xDocumentClass element.
Its format is ####.####.####.#### (major.minor.revision.build). The version number of the .xsf file allows Microsoft Office InfoPath 2003 to determine whether the current form is compatible with the product version in which it is being opened.
