Error with Schema/API output regarding elementFormDefault="qualified"

[paulo-graca]

Like #2 , I think this isn't the proper place to report this, but if you can do the favor to address to the right people, I would be much appreciated!

The schema https://www.openaire.eu/schema/1.0/oaf-project-1.0.xsd is defined as elementFormDefault="qualified" but the OpenAIRE API return non qualified elements like:

https://api.openaire.eu/search/projects?grantID=110062&funder=FCT

</oaf:entity>

if the API truly validates against the schema, the element:
<code>110062</code>
should instead be:
<oaf:code>110062</oaf:code>

to be in accordance, the API should change or the schema should be changed to be more permissive, changing https://www.openaire.eu/schema/1.0/oaf-project-1.0.xsd from the defined elementFormDefault="qualified" to elementFormDefault="unqualified"
