Ordered Association for XML Schema

[henmanworking]

Hi

I`ve got a problem.

I build a class diagramm for a existing standard XML Schema.
In the Schema i have a generalize Association. For the Validation of XML Files it is important, that the tags are in the right order. My generalize Associations are sometimes at the beginning and sometime at the end. But i need the generalized complextype at a special point.

I have this problem also bei Choice and Sequenzes with multiplicity.

Have anyone a solution?

Thanks Henry
