UML Profile - possible to embed data-types?

[PaulR]

Hi, new user of Enterprise Architect here.

I'm trying to set up a UML Profile for Data Modelling. At the moment, it contains just basic elements, but I have a stereotype of Class called 'Data Type'. Within this stereotype I'd like to embed datatypes such as the W3C standards, together with other customised types - so that people using the Profile will have them available to use.

I can't seem to find a way of achieving this - at the moment I have the W3C datatypes under the stereotype of DataType in the Project Browser, but when you import the UML Profile, the datatypes don't seem to be carried across (indeed, they don't feature in the XML file).

Any suggestions?

Thanks!
