The recent state of stereotype support includes implicit the attribute if a
related stereotype is present or not, which theoretical could be also expressed
as an explicit attribute  "present=yes|no" (I'm not saying that we should
implement that, it is only for understanding) 

To support uml 1.4 tagged values, it is required
1. to add a key/value map to class UMLStereotype
2. to extend stereotype xmi  save/load with this map
3. to adapt client code to use UMLStereotype class if not done 
4. to extend the property dialog of class UMLStereotype
5. to extend the property dialogs supporting stereotypes to add/change
stereotype attributes

Just a few ideas:
3.   by using UMLStereotype::name() to get the name 
 5. may be implemented by replacing the current widget code shown below
Classgeneralpage::Classgeneralpage()
... 
    m_pStereoTypeL = new QLabel(i18n("&Stereotype name:"), this);
    m_pNameLayout->addWidget(m_pStereoTypeL, 1, 0);

    m_pStereoTypeCB = new KComboBox(true, this);
    m_pNameLayout->addWidget(m_pStereoTypeCB, 1, 1);

    m_pStereoTypeCB->setItemText(m_pStereoTypeCB->currentIndex(),
m_pObject->stereotype());
    m_pStereoTypeL->setBuddy(m_pStereoTypeCB);

  if (t == UMLObject::ot_Interface || t == UMLObject::ot_Datatype || t ==
UMLObject::ot_Enum)  {
        m_pStereoTypeCB->setEditable(false);

...

by a new dedicated dialog widget class located in
umbrello/dialogs/widgets/umlstereotype.cpp
  UMLStereotypeWidget *widget = new UMLStereotypeWidget
(m_pObject->stereotype());
  if (t == UMLObject::ot_Interface || t == UMLObject::ot_Datatype || t ==
UMLObject::ot_Enum) 
     widget->setEditable(false);
 m_pNameLayout->addWidget(widget);

the latter would also be a preparation for future properties editor support
(see bug 97291)

For full uml 2.0 support it is additional required to support profiles. On a
first run profile support could be reduced to a hard coded default profile
using the current implementation.

BTW: Umbrello supports already a kind of profile support in the code generation
area (one profile for each language)

This is very useful
