A GNS label is a label as defined in <xref target="RFC8499"/>.
It is always assumed to be a U-label as
defined in <xref target="RFC5890"/> and <xref target="RFC5891"/>.
- Consequently, labels are case-sensitive UTF-8 strings in Unicode

Normalization Form C (NFC) <xref target="Unicode-UAX15"/>.
GNS does not impose length restrictions on labels. However, applications
MAY ensure that name and label lengths are compatible with legacy
DNS.
- <!-- FIXME U-labels MUST not be too long. Their A-label representation
- must fit into a DNS label. Do we want this limitation for GNS?
- Or do we define "compatibility" labels that follow this limitation?

+ In the spirit of <xref target="RFC5895"/>, applications MAY preprocess
