This software was installed from the copy distributed on the SGML’97 CD-ROM. However, the INSTALL and readme files referenced binaries that were not included, and attempting to parse any of the test suite resulted in references to components that were not recognised. However, the vm2 program did appear to execute, but failed to parse the sample file, returning error messages related to capacities, and it was not clear how the values from the SGML Declaration could be implemented within the time available.
