Umbrello lacks support for Parameterized Class
(Template) as defined in chapter 3.29 (page 49) of the
UML 1.3 standard.

Other categories affected:
Code generation
Code parser
Diagram drawing

This is a very important feature when doing designs for
implementation in C++ where templates are widely used.
Not all C++ developers use templates in their code, but
it's getting more and more common. Umbrello is
currently useless for me because my code is not
properly reverse engineered, neither can I do new
designs using templates.

Parametrized Classes are also making their way into the
next Java (JDK1.5):
