[CF-metadata] Time for 1.0 revision xxx or version 1.1 ?

The proposed rules for changes says:

But nothing about the actual version number scheme. There has been some 
discussion on the list but I'm wondering if it would be worth spelling 
out some version numbering policy in the change rules. Perhaps a 
paragraph following the above that looks something like:

    Version numbering follows a standard <major>.<minor>[.<maintenance>]
    format. Only the major and minor version numbers are included in the
    "Conventions" global attribute value, "CF-<major>.<minor>". The
    maintenance version number is incremented for changes that will not
    affect software or format. The minor version number is incremented
    for changes that are backward compatible (i.e., an extension to the
    existing convention). The major version number is incremented for
    any changes that would break existing software or cause existing
    datasets to be invalid.
