2.1.393 Part 4 Section 18.104.22.168, autoCaption (Single Automatic Captioning Setting)
a. The standard places no restrictions on the conditions under which this element is to be used.
Word only reads this element when it is stored within the default document template.
b. The standard states that the name attribute specifies a unique identifier for types of objects to be automatically captioned.
Word writes and expects wfwTables for Microsoft Word Tables, and the key name of the OLE object for OLE objects (the key name is stored in the Windows registry under HKEY_CLASSES_ROOT).
c. The standard states that the name attribute and the caption attribute can contain a string of unlimited length.
Word limits these values to 255 characters.
