I am not sure if what you want is:

a ) include in the document a diagram, but only showing part of the elements in the diagram

There is a operation defined in the GMF bundle defined for this purpose: getDiagram(d : notation::Diagram, elements : Sequence(OclAny)) which produce the image of the diagram hidding all the elements that are not provided as second element.

You can use it in a template as:

<image object="d.getDiagram(<ocl expression selecting the elements to display>)" ...>
...
</image>

Trying that function today I come into a issue (Bug 509948) that prevent this approach to work in some cases.

b) If you want use a diagram to access the elements that are shown in the diagram:

In this case just use 'd.getElementsInDiagram()' in a for, something like that:

[for (p : uml::Package | d.getElementsInDiagram()->filter(uml::Package))]
...
[/for]

Regards,
Antonio

Hello I agree with Antonio's answer
A bug has to be opened but take care you have to give a sequence :
- so it is generally needed to do <ocl expression>->asSequence()
