In the type chapter, the grammar for field specifiers of shape types is:

shape-specifier:
  shape ( field-specifier-list-opt )
field-specifier-list:
  field-specifier
  field-specifier-list  ,  field-specifier

But this is allowed to have a trailing comma. Probably the grammar should be something like:

shape-specifier:
  shape ( field-specifier-list-opt )
field-specifier-list:
  field-specifiers  ,-opt
field-specifiers:
  field-specifier
  field-specifiers  ,  field-specifier
