XMI13 — More use of schema structural constraints

  • Key: XMI13-1
  • Legacy Issue Number: 4638
  • Status: open  
  • Source: gmail.com ( Barbara Price)
  • Summary:

    It is not clear why a separate XML construct has not been used for proxies
    (as described in 4.9) - rather than leaving an importer to check for the
    presence of link attributes. And providing no Schema-level enforceable
    constraint that proxies have no content (and vice versa).
    It would also help to have a stronger statement with respect to the use of
    XMI attributes as a 'cache' within proxies: to what extent must they be
    accurate and what options does an importer have if they are not? Does
    validation include checking the accuracy of cached attributes?
    4.6.2: Could Schema mechanisms be used to enforce the constraint that only
    one of href and idref is to be used?
