Re: [docbook] Add "danger" to the list of possible admonitions?

[Bob Stayton <bobs@sagehill.net>]

Actually, DocBook has long used this "other" method to extend some 
enumerated attribute values.

On section elements:
renderas="other"
otherrenderas="..."

On <orgname>:
class="other"
otherclass="..."

On <biblioid>, <citebiblioid>, <bibliosource>, <bibliorelation>
class="other"
otherclass="..."

On <bibliorelation>:
type="othertype"
othertype="..."

There are others as well.

In the case of admonitions, the original DocBook authors chose to use 
separate elements for the different types, instead of a single element 
with an enumerated attribute.  It is too late now to switch.  I 
generally suggest adding @role to one of the existing elements, or 
extend the schema.
