Thank you very much for these links...

hmm, when reading through them I noticed something... is
fields=uuid;actual-equipment(manufactured-thing(equipment-type);structure)
even valid?

According to the RFC8040 4.8.3. the bracket part of the expression can
only nest in the last of the fields...

'path ; fields-expr', but not 'fields-expr ; path"

What do you think ? I guess this was don to prevent a whole tree of
field subexpressions... the ABNF does only seem to support a "line" of
them.
