The 'category' property from katedec is that 'purpose/use type' you need.
A list of well known category types is available at
wiki.xiph.org/index.php/OggText
In VLC, I fill the subtitles list menu with, for all streams:
<language> <category>
Category is a textual code, so may be translated in the user's language,
so for category 'LRC' and language 'de', you'd get:
German lyrics
for an English user.

As for the slides thing (category K-SLD-I, not in the well defined
list for now), I have them displaying on a second window in VLC (in
a local patch, it's unwieldy, and unfinished). Actual presentation
would be up to the client, but I'd imagine that if the stream is
enabled, new slides would go fullscreen for a few seconds when the
presenter switches to them, then zooming out back to a corner to
have them as a clickable zoom in/out icon would be a nice way to
do it, for a video player wanting to do presentations.

As a side note, if subtitles were also present, they'd typically be
in a separate stream, as text.
