Re: [Yaml-core] Special Keys mentioned on http://www.yaml.org/refcard.html

[Clark C. E. <cc...@cl...>]

These are definately not meant to be part of the core specification,
they are optional data types which could be registered and handled
in a post-processor that knows about them.

    http://yaml.org/type/value.html
and http://yaml.org/type/merge.html

I have found these keys to be quite useful.  The !!value data type
provides a way to "upgrade" an application expecting a given node
to have a single value to a mapping.  The !!merge is a simple
data inheritance mechanism.=20

Best,

Clark
