Even if I use the scale denominator I have to repeat the class for each
category for every priority.
The style of each category remain still the same, which means I have a
lot of duplicated classes.

I wonder if you could access the current computed scale denominator in
expression (or the DATA statement) and get the same effect...
e.g.:
CLASS
EXPRESSION ('[category]' eq 'poi'&& [priority]< SCALE)
...
END

Hi Steve,
maybe it's easier to explain with a mapfile example:
LAYER
NAME "POI"
TYPE POINT
CONNECTIONTYPE postgis
CONNECTION "user=somebody password=something dbname=test
host=localhost"
DATA "the_geom FROM (SELECT gid, category, priority, the_geom FROM
poi) AS foo USING UNIQUE gid"
...
CLASS
EXPRESSION ('[category]' eq 'poi')
MAXSCALEDENOM [priority]
...
END
...
END
In this case I've one single class for each category and the
MAXSCALEDENOM get the value from the priority attribute of my datasource.
As it is now, MapServer does not support this feature and I've to repeat
every single category for each different priority value.
Best regards,
Daniel

MapServer doesn't support layer-level binding only feature-level binding. I'm
having trouble seeing the value. Can you explain further?

Hi,
I've tried to read the MAXSCALEDENOM value from a attribute in my
datasource, but mapserver throw's a parsing error.
Probably because such feature does not exist in mapserver.
Are there any intentions to implement this?
It could be interesting for layers, whose data has different priorities
but the same styling.
With this feature I can avoid repeating the classes for every priority.
Best regards,
Daniel
