It's not limited however it ships with a handful of common predefined services 
for convenience. You can find them in `/usr/lib/firewalld/services` and use 
them as a template and create one for `ws-discovery` if you like. Here is an 
example one you could place in `/etc/firewalld/services/ws-discovery.xml` which 
would allow you to refernece `ws-discovery` in future rules.

```
<?xml version="1.0" encoding="utf-8"?>
<service>
  <short>ws-discovery</short>
  <description>Web Services Dynamic Discovery</description>
  <port port="3702" protocol="tcp"/>
  <port port="3702" protocol="udp"/>
</service>
```
