While this is sufficient for the current use case, what if we want to render two or more XMI files in a document? Then we need to name them just like in lutaml-express (as document attributes).

If we do that, in declaration we define the "short name" of the XMI, location of XMI and also the base path for images. Then when we want an image, we just say for example, "image 1 in XMI 1".

Ping @kwkwan for an enhancement issue to move the definition into the header. We do not want to specify the XMI file for every single image we refer to, the line becomes too long. The XMI only needs to be loaded once.

An issue (metanorma/metanorma-plugin-lutaml#170) has been created for this enhancement.

The macro lutaml_ea_diagram will refer to the XMI file loaded by lutaml_ea_xmi. Thus, the XMI document is loaded once.
