Description:
In the output from ndb_config --xml --configinfo, the transporter sections 'TCP', 'TCP
DEFAULT', 'SCI', 'SCI DEFAULT', 'SHM', and 'SHM DEFAULT' are listed. 

The non-TCP sections are only for internal use, and could be deleted from the output from
ndb_config. Alternatively, if they are still listed in the output, they should be marked
with an attribute in the element tag, e.g. supported="false", internal="true", or
something similar. 

As an example: <section name="SHM default" comment="shared memory options for ndb data
nodes" supported="false">

This applies to sections 'SCI', 'SCI DEFAULT', 'SHM', and 'SHM DEFAULT'. 

How to repeat:
Current output from ndb_config does not distinguish between the sections.

At http://dev.mysql.com/doc/refman/5.1/en/mysql-cluster-interconnects.html SCI and SHM
connections listed as supported.

Thank you for the report.

Verified SHM part as it is experimental and SCI is supported.

Following up on the previous IRC discussion i'd like to suggest a general optional

  supported=yes|no|experimental|deprecated 

attribute for all configinfo tags which would default to "yes" ...

The deprectade configuration options are not printed out. And I think "experimental" is
just a nice word for "no", will use experimental.

Documented bugfic in the NDB-6.3.29 and 7.0.10 changelogs as follows:

        ndb_config --xml --configinfo now indicates that parameters
        belonging in the [TCP], [TCP DEFAULT], [SCI], [SCI DEFAULT],
        [SHM], and [SHM DEFAULT] sections of the config.ini file are
        deprecated or experimental, as appropriate.

I honestly hope I didn't mark [TCP] as "experimental"

        ndb_config --xml --configinfo now indicates that parameters
        belonging in the [SCI], [SCI DEFAULT], [SHM], and [SHM DEFAULT]
