"Various web pages"? Where exactly?

An SRV record without a matching TXT record is not a valid DNS-SD
service, hence Avahi will treat this as an error. If you don't need
the TXT record, than set it a single empty string.

Avahi can be used to resolve non-DNS-SD SRV records: just pass
AVAHI_LOOKUP_NO_TXT in the flags argument and pass NULL as service
name and use the normal service resolver.
