[Idea] page on xml extensions

[stevieflow]

Is your feature request related to a problem? Please describe.

The current dashboard surfaces the use of extensions via the elements / attributes breakdowns. This isn't great to get to an overview of the extensions being used by publishers

Describe the solution you'd like

• Provide a new page "Extensions" in the dashboard
• List the (unique) namespaces declared - and who/how many publishers use this
• List the subsequent parent element where these namespaces sit
• List the subsequent elements/attributes that use these namespaces

Describe alternatives you've considered

Additional context

More widely, this would help lay the foundation for codeforIATI/iati-ideas#29

Ooh – I wonder if this relates to IATI/IATI-Dashboard issues 432 and 123…

Agree!

I think step 1 here is to determine standard vs non-standard elements and attributes. After that, we can start splitting out extension elements.

We can potentially use https://pypi.org/project/xmlschema/ for this (@kindly mentioned this on discord recently, as he has been using it).

Failing that, we can definitely use this: https://github.com/codeforIATI/reference/blob/3e8a12c8/schema_to_doc.py#L270

^^ I’ve started this here: https://analytics-dev.codeforiati.org/elements.html

First attempt looks wrong – it’s currently only checking against the v1.05 activities schema. That shoudl be fixed in the next build. Fixed now
