"For a scalable font source, a scalable font name for each

the scalable font name, specific derived instance names
may also be included in the list."

"Because some existing applications rely on seeing a collection
of point and pixel sizes, server vendors are strongly
encouraged in the near term to provide a mechanism for
including, for each scalable font name, a set of specific
derived instance names. For font sources that contain a set of
specific derived instance names."
So it is OK to have that in font list. It must be --0-0- base
name for every such font, and if it is not -- there is an error
somewhere in your X server or font server, and probably should be
fixed. If there are base entries -- then you don't need them.

I don't really need it, existing choice is big enough !
Probably you somewhat misread my description.
It should be not big enough, it should contain all that fonts
with proper fields zeroed.
If it does not -- it is some error in server.
But I only wanted to know the signification of "0" field in -adobe-new
century schoolbook-bold-r-normal--0-120-100-100-p-0-iso10646-1
I did these (easy to reproduce) tests with xfontsel and xlsfonts commands
:
xfontsel :
- if we select a point size of 120, it's impossible to select a pixel size
of 0
- if we select a pixel size of 0, we only have the choice between * or 0
for point size
xlsfonts :
- xlsfonts -fn "-*-*-*-*-*-*-0-*-*-*-*-*-*-*" (pixel size of 0) : we can
see scalable fonts and fonts like -adobe-new century
schoolbook-bold-r-normal--0-120-100-100-p-0-iso10646-1
- xlsfonts -fn "-*-*-*-*-*-*-0-120-*-*-*-*-*-*" (pixel size of 0, point
size of 120) : we can see fonts like -adobe-new century
schoolbook-bold-r-normal--0-120-100-100-p-0-iso10646-1
- xlsfonts -fn "-*-*-*-*-*-*-*-120-*-*-*-*-*-*" (point size of 120) :we
don't see anymore fonts like -adobe-new century
schoolbook-bold-r-normal--0-120-100-100-p-0-iso10646-1, which is confusing
because "-*-120-" also matches "-0-120-"

There is no server error.
The answer is at the end of chapter 5 of
https://www.x.org/releases/X11R7.7/doc/xorg-docs/xlfd/xlfd.html#Scalable_Fonts
where it is said:
"if the actual pattern argument (of ListFonts X query) has values
containing no wildcards in scalable fields, then substitute each such
field into the corresponding field in each scalable font name in the list."
So as I understand, if we call xlsfonts -fn
"-*-*-*-*-*-*-0-0-*-*-*-0-*-*" (Pixel size, point size and average width
at 0), we get all scalable fonts, and if we call xlsfonts -fn
"-*-*-*-*-*-*-0-138-*-*-*-*-*-*" (Pixel size at 0 and point size of 138)
or xlsfonts -fn "-*-*-*-*-*-*-*-138-*-*-*-0-*-*" (Point size of 138 and
average size at 0), we get all scalable font *instances* with a point
size of 138 and some default resolutions.
120 seems to be something like a default point size value and 17 a
default pixel size when these values are not specified. try to call
xlsfonts -fn "-*-*-*-*-*-*-0-*-*-*-*-*-*-*" or xlsfonts -fn
"-*-*-*-*-*-*-*-0-*-*-*-*-*-*"
I already thank you Ilya for your help and spoting to the XLFD doc that
is not easy to find
