Export to ims qti erases external references

[clavisound]

Hello guys, thank you for the great platform.

Let's say we have a question with a photo to external URL
<img src="https://mydomain/image.png" />

Export to QTI erases the external reference, although the external reference is working properly in openeclass.

According to QTI specication, seems possible.

uri The uri attribute is used to identify an external resource i.e. typically a file name or URL. An alternative, and preferred method is the usage of the entityref attribute.
