I believe you're describing the following feature described at

In APRSISCE/32, I'm calling that "filtered" -IS to RF gating. This is
not required but is allowed by the specification. What I've read that
xastir implements for -IS to RF gating is described as:

Where "message packets" are the APRS-specified messages defined by
datatype : (colon) and described in Chapter 14 of aprs101.pdf.
