I saw in your RDF schema that you have enc:enclosures as subclass of 
rdf:Seq:

<rdfs:Class rdf:about="#enclosures" rdfs:label="Enclosures">
   <rdfs:subClassOf rdf:resource="&rdf;Seq"/>
</rdfs:Class>

Whilst in your example you don't use it as such:

<enc1:enclosures 
rdf:about="http://crocodile.org/ns/rss/1.0/enc/ex/#enclosures_music">
   <enc1:kind>alternative</enc1:kind>
   <enc1:children>
     <rdf:Seq>
       <rdf:li 
rdf:resource="http://crocodile.org/ns/rss/1.0/enc/ex/#matrosi.mp3" />
       <rdf:li 
rdf:resource="http://crocodile.org/ns/rss/1.0/enc/ex/#matrosi.ra" />
     </rdf:Seq>
   </enc1:children>
</enc1:enclosures>

Using it as subclass of rdf:Seq would look more like:

<enc1:children>
   <enc1:enclosures>
     <rdf:li 
rdf:resource="http://crocodile.org/ns/rss/1.0/enc/ex/#matrosi.mp3" />
     <rdf:li 
rdf:resource="http://crocodile.org/ns/rss/1.0/enc/ex/#matrosi.ra" />
   </enc1:enclosures>
</enc1:children>

Looking at your <enc1:kind/> i think you can implement this with 
standard RDF collections:

<!-- Ordered list -->
<enc1:children>
   <rdf:Seq>
     <rdf:li 
rdf:resource="http://crocodile.org/ns/rss/1.0/enc/ex/#matrosi.mp3" />
     <rdf:li 
rdf:resource="http://crocodile.org/ns/rss/1.0/enc/ex/#matrosi.ra" />
   </rdf:Seq>
</enc1:children>

<!-- Unordered list -->
<enc1:children>
   <rdf:Bag>
     <rdf:li 
rdf:resource="http://crocodile.org/ns/rss/1.0/enc/ex/#matrosi.mp3" />
     <rdf:li 
rdf:resource="http://crocodile.org/ns/rss/1.0/enc/ex/#matrosi.ra" />
   </rdf:Bag>
</enc1:children>

<!-- Alternatives -->
<enc1:children>
   <rdf:Alt>
     <rdf:li 
rdf:resource="http://crocodile.org/ns/rss/1.0/enc/ex/#matrosi.mp3" />
     <rdf:li 
rdf:resource="http://crocodile.org/ns/rss/1.0/enc/ex/#matrosi.ra" />
   </rdf:Alt>
</enc1:children>

Using my own schema i would most likely take the following approach:

<rss:item>
   ...
   <enc:enclosures>
     <rdf:Seq>
       <rdf:li>
         <enc:Enclosure>
           <enc:url>http://foo.bar/baz.mp3</enc:url>
           <enc:type>audio/mpeg</enc:type>
         </enc:Enclosure>
       </rdf:li>
       <rdf:li>
         <enc:Enclosure>
           <enc:url>http://foo.bar/bat.mp3</enc:url>
           <enc:type>audio/mpeg</enc:type>
         </enc:Enclosure>
       </rdf:li>
       <rdf:li>
         <enc:Enclosure>
           <enc:url>http://foo.bar/cat.mp3</enc:url>
           <enc:type>audio/mpeg</enc:type>
         </enc:Enclosure>
       </rdf:li>
     </rdf:Seq>
   </enc:enclosures>
</rss:item>

This would only need the addition of an <enc:enclosures/> property in 
my schema.
