You are using nodes and attributes rather than simply nodes but the end game is essentially the same. I'm not sure if English is your first language but I didn't quite understand what you are asking.

Do you need to know how to embed the xml file into a document or are you asking how to make the attribute editable inside the Word document? Are you doing this purely with VBA or do you want to use the Word GUI to achieve the end game?

Note that the 'image' file type is actually a string. You won't be able to include a PNG image in a text only format which is necessary for xml.
