>>>From the current TAPIR schema, concept ids follow the
"qualifiedConceptIdType", which is explained as:
"A simpleType to represent qualified concept identifiers. This can
either be the full format NAMESPACE#LOCAL_CONCEPT or an alias which
can be any string."
So you're right that local concepts may not use XPath. It's a choice.
I was just following Markus examples - no intention to suggest how
the "gcp" conceptual schema should identify its concepts.
Now looking at the "simpleXPathType" (used by the node's path
attribute) it seems that the string restriction does not allow for
namespace prefixes. So I guess this is something that needs to be
fixed in the schema.

The WFS response is only the responded view/data model and we would still just use gcp#accession/FullScientificName as the qualified concept in filters. This is also true for our simple extension schemas I think (EFG for ABCD, all extensions for DwC). But arent there other cases?
