Hi,

I am reading a UML2 XMI model that contains < and &
in the names of UML model elements (it is a C++ model
and it contains, for example, an operator< method).

When trying to read this via the Eclipse UML tooling,
the parser dies and says something about illegal char-
acters. The same is true for the & in names (like in
C++ reference attributes).

Any idea what I can do?

Thanks,
Markus

I was just going to say that probably those characters were not properly
encoded as they should given that they are XML predefined entities, but
then I just tried to open both a .xmi file and a .uml having "<", "&"
and ">" in operation names and they opened just fine (see attachment),
regardless those characters where encoded as entities or not, I guess
because they appear in attributes, not as nodes.

Can you provide an example of a model that you can't load?

Cheers,

Rafael
