Define Transform Message metadata using raml datatype

Hi,

I have a 2 part question

a. How do I define metadata of a Transform Message component using the available RAML datatypes, instead of a JSON schema / example? Is this possible?

b. How do I import the import the 'accounts-mod04-api-implementation-solution' project into my Anypoint Studio?

What I've tried so far has resulted in an incomplete project where the source/main/api folder is empty - the accounts-api.raml and the associated examples and datatypes are not loaded into studio.

This is related to the 'Building APIs' section of the MuleSoft.U Development Fundamentals (Mule 3) course.

Thank you!
