The underlying C++ API 'specdef' defining the form.
The C++ 'specdef' that defines the format of the spec.
The SpecDef is a formatted string that Perforce uses internally to parse forms. SpecDefs will vary by form, server version, and even with specific server configurations. In general, you should avoid using a SpecDef directly; however, in some cases you can avoid a server call by using the SpecDef.
