<service-group> The document tag of avahi
service files. Should contain one <name> and one or more
<service> elements.
<name replace-wildcards="yes|no"> The
service name. If replace-wildcards is "yes", any
occurence of the string "%h" will be replaced by the local
host name. This can be used for service names like "Remote
Terminal on %h". If replace-wildcards is not
specified, defaults to "no".
<service protocol="ipv4|ipv6|any">
Contains the service information for exactly one service
type. Should contain one <type> and one
<port> element. Optionally it may contain one
<domain-name> , one
<host-name> , any number of
<subtype> and any number of
<txt-record> elements. The attribute
protocol specifies the protocol to advertise the
service on. If any is used (which is the default),
the service will be advertised on both IPv4 and IPv6.
<type> Contains the DNS-SD service type for this service. e.g. "_http._tcp".
<subtype> Contains an additional DNS-SD service subtype for this service. e.g. "_anon._sub._ftp._tcp".
<domain-name> The domain name this service
should be registered. If omited defaults to the default domain
of the avahi daemon. (probably .local)
<host-name> The host name of the host that
provides this service. This should be a host that is
resolvable by multicast or unicast DNS. Please note that you
need to specify a fully-qualified domain name (FQDN) here,
i.e. .local is not appended implicitly! The host name doesn't
need to be part of the domain specified in
<domain-name> . See
<port> The IP port number the service listens on.
<txt-record> DNS-SD TXT record data.
