I'm still not very familiar with what this whole stylesheet is doing.
What I'm getting at is other node tags (like amenity=) look like this:

<Style name="text">
      <Filter>[place] = 'island'</Filter>
      <TextSymbolizer name="name" fontset_name="oblique-fonts"
size="9" fill="#000" dy="0" halo_radius="1" wrap_width="0"/>

But turning_circle looks like this:

<Layer name="turning_circle" status="on" srs="&osm2pgsql_projection;">
      <Parameter name="table">(select way from &prefix;_point where
highway='turning_circle') as turning_circle</Parameter>

What's the fundamental difference that makes them get implemented this
way? Something to do with the data coming from osm2pgsql.

Sorry for the noob questions, I'm trying to absorb a lot of
information quite quickly.
