Failed validation of voidable LC nomenclatur elements embedded/external description

[FrLemmel]

Hi,

I am currently trying to validate a preliminary GML for AII LCV data. I run into the issue that the validator reports a missing embedded or external description when testing against the LCN schema.
Looking at the UML Model it becomes apparent, that these elements are voidable. Hence, I am a bit confused on how to solve this issue and make the GML valid. The attached zip contains the .gml file currently tested.

lc_to_gml.zip

And here is the latest test report:
https://inspire.ec.europa.eu/validator/test-run/details.html?id=EID7d47d0ee-98dd-4a97-a9ca-36296c2a08e5

There is also the error of GML and INSPIRE GML Application Schema validation. Might this be in relation to the above mentioned error ?

Unfortnuately I cannot run any tests in the staging environment, as I am not prompted further after setting al the parameters.

Dear @FrLemmel,

I had a look at your dataset and it contains the following errors:

1. Dates of the beginLifespanVersion attribute are wrong because the dataType of this eleemnt is dateTime, so they should have the following format: 2018-05-20T00:00:00
2. The schemaLocation attribute should contain the declaration of the gml schema since the validator is not able to retrieve it from the INSPIRE schema, so it should be: xsi:schemaLocation="http://inspire.ec.europa.eu/schemas/lcv/4.0 http://inspire.ec.europa.eu/schemas/lcv/4.0/LandCoverVector.xsd http://www.opengis.net/gml/3.2 http://schemas.opengis.net/gml/3.2.1/gml.xsd">
3. The embedded description OR the external description shall be provided. Even if the two attributes are voidable and have multiplicity equal to zero, there is a constraint that requires one of the two (see screenshot below).

I hope that this helps to clarify.

Thanks @fabiovinci for clarification. I will try to implement it in the following days and re-check with the validator. If needed I will come back to this ticket or close it when being successful.
