TOSCA Node Template key types

[Miguel Caballer <micafer1@upv.es>]

Hi,

I have some comment about the definition of the TOSCA Node Template 
keynames in the TOSCA YAML (versions 1.0, 1.1 and 1.2).

And as described in sections 3.7.3.1 (versions 1.0 and 1.1) or 3.8.3.1 
(version 1.2).

The type of: properties, attributes, capabilities, interfaces and 
artifacts is "list of ..." but in all the examples and TOSCA documents 
available they are actually defined as "maps".

There are some misleading information.

Best regards.
