If the standard is to be amended with a new {key,value}
pair which
should be applicable to all supporting parties, a group discussion
will take place. This is the preferred method for introducing
changes. If one particular party wishes to add a field for personal
use, they should prefix the key with the string X-
,
e.g. PRODUCT
X-NewDesktop-Foo
, following the precedent set by other IETF and RFC
standards.
Alternatively, fields can be placed in their own group, where they may
then have arbitrary key names. If this is the case, the group should
follow the scheme outlined above,
i.e. [X-
or
something similar. These steps will avoid namespace clashes between
different yet similar environments.
