gmlas.c.1: Test fails because "uom" element does not contain a value

[florianesser]

The test file soillayer_should_validate.zip fails gmlas.c.1 with the following message:

The dataset has 1 feature(s) with errors for this assertion.
XML document 'soillayer_should_validate.gml', SoilLayer '': The following properties of the feature have an empty value: uom. While this is valid against the XML schema, this is not valid according to the GML model. Please correct the process that generates the GML documents.

(full test report: XML, HTML)

The uom element in question (<so:uom uom="m"></so:uom>), however, must not have a value (definition of gml:UnitOfMeasureType here).

If a value is assigned (e.g. <so:uom uom="m">m</so:uom>), gmlas.b.2 gives the following error:

cvc-complex-type.2.1: Element 'so:uom' must have no character or element information item [children], because the type's content type is empty.
