- :iscman:`dig` fails to parse a valid (as far as I can tell, and accepted by
- `kdig` and `Wireshark`) `SVCB` record with a `dohpath` URI template
- containing a `{&dns}`, like `dohpath=/some/path?:FIXME-rndcconf-namedconf:`key`=value{&dns}"`. If
- the URI template contains a `{?dns}` instead :iscman:`dig` is happy, but my
- understanding of rfc9461 and section 1.2. "Levels and Expression
- Types" of rfc6570 is that `{&dns}` is valid. See for example section
- 1.2. "Levels and Expression Types" of rfc6570.
+- `{&dns}` is as valid as `{?dns}` in a SVCB's dohpath.
- Note that Peter van Dijk suggested that `{dns}` and
- `{dns,someothervar}` might be valid forms as well, so my patch might
