Actually, there is a way, and it is being used quite a few places.

To point to i.e. an RSS channel:

<rdfs:seeAlso>
  <rss:channel rdf:about="http://example.com/myfeed.rdf"/>
</rdfs:seeAlso>

Another way to say the same thing:
<rdfs:seeAlso rdf:resource="http://example.com/myfeed.rdf";
rdf:type="http://purl.org/rss/1.0/channel"/>

Basically what could work here is to define a "list of feeds" class,
say http://example.org/feeds#list and then say:

<f:list xmlns:f="http://example.org/feeds#"; rdf:about="">
  <rdfs:seeAlso rdf:resource="http://example.com/myfeed.rdf";
  dc:title="My Feed"
  rdf:type="http://purl.org/rss/1.0/channel"/>
  <rdfs:seeAlso rdf:resource="http://example.com/mycomments.rdf";
  dc:title="My Comments"
  rdf:type="http://purl.org/rss/1.0/channel"/>
<f:list>

There you go, an extensible feed list format, compatible with existing
infrastructure... :)
