FCS-QL seems to use "word" instead of "text" for surface layers

[Akron]

When using the visual query builder for FCS, the query uses "word" as the layer for surface forms instead of the supported "text". FCS always returns status code: 6, reason phrase: Layer word is unsupported. for KorAP. Other instances have the same problem, so I guess the specification has changed. There is also a problem, that the POS annotations are limited to the UD POS values. So it may be beneficial to add a UD->STTS mapping as part of SRU.
