Discussion about read- write-/multipleproperties

In the Scripting API call we did have an interesting discussion about what does op readmultipleproperties mean. We did have the feeling that the TD spec is not super clear about that case. I tried to look into it and found the following para (last para in 5.3.1.1 Thing)

If not specified otherwise (e.g., through a TD Context Extension), the request data of the readmultipleproperties operation is an Array that contains the intended PropertyAffordances instance names, which is serialized to the content type specified by the Form instance.

This seems to match with what we have in https://w3c.github.io/wot-scripting-api/#the-readmultipleproperties-method. There needs to be a dedicated form with op being readmultipleproperties and one can specify an array of property names.
Does everybody agree?

In the case of writemultipleproperties it is the same I think.

Start by comparing the cited Thing Description section with the Scripting API readmultipleproperties method, then review the discussion about writemultipleproperties. Done requires resolving whether the stated request format and dedicated forms are correct and recording the agreed interpretation in the relevant specification text.
