Warnings thrown when using namespace xml

[ChrisSchoe]

Describe the Bug
When importing a diagram that uses the namespace xmlns:xml without explicitly declaring it warnings are thrown.
My understanding so far was that this namespace should be included by default in all xml files.

This issue is coming from running tests for the upcoming bpmn miwg demo.

Steps to Reproduce

• import the file
• note the numerous warnings thrown due to the nested error "missing namespace for prefix "

Adding xmlns:xml="http://www.w3.org/XML/1998/namespace" to the definitions removes these warnings.

Expected Behavior

As far as I understand it the standard xml namespace should be included by default in all xmls. Thus, no warnings should be shown if it is not explicitly named in the definitions.

Environment

• Browser FF 75
• OS: Win 10
• Library version: 6.4.2

Depends on bpmn-io/moddle-xml#50

You could also rename your diagram to .bpmn.txt and upload it directly (without archiving).

Ah, that makes sense. Thank you, I'll do that next time.

I have provided a PR which should fix this issue: bpmn-io/moddle-xml#51

[ChrisSchoe]

I tested an adapted version of @onlineandy 's fix for moddle-xml v 8.0.7 in combination with bpmn-js, worked great!

[nikku]

Upstream issue bpmn-io/moddle-xml#50 fixed.

We'll cut patch releases of the required libraries. In the mean time, you may:

npm update --depth=10 moddle-xml

...to get your bpmn-js version fixed.

Fixed in bpmn-js@7.0.1
