Hello Jorge,
 Verry thanks for your reply; Ive experimented a little with "opt_flag",
but obtained no expected results :(

That is terrible thing that "opt_flag"
Description:	
Control the layer display process. Add the values below to acquire the desired options (default is 15):
1:	If set, show layer even if out of scale (default: hide layers out of scale).
2:	If set, show layer even if status is OFF (default: hide layers with STATUS OFF).
4:	If set, show layer even if type is QUERY (default: hide layers of TYPE QUERY)
8:	If set, show layer even if type is ANNOTATION (default: hide layers of TYPE ANNOTATION)

my conclusions:
   settings:   0  1  2  4  8 14 15
1 outofscale   +  +  +  +  +  +  +  
2 off          -  -  +  -  -  +  +  
4 query        ?  ?  ?  ?  ?  ?  ? 
8 annotation   ?  ?  ?  ?  ?  ?  ?

Ive found this mail:
http://mapserver.gis.umn.edu/data2/wilma/mapserver-users/0210/msg00037.html
here is told (as i understood my english is considerably retarded) that this behavior depends on:

group names
layer names and scales
class names and scales
the option code in legend templates...

-- which is horrible :(

mail is written in 2002. my compilation is:
alnagon ~ % /var/www/localhost/cgi-bin/mapserv -v
MapServer version 4.8.3 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP
OUTPUT=PDF OUTPUT=SWF OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=FREETYPE

SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER SUPPORTS=GEOS INPUT=TIFF
INPUT=EPPL7 INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE

Is there some example on the internet where is hiding of invisible
classes in html legend sucessfully used ?
