Properly testing input multiplicity

[jerstlouis]

Describe the bug
The ETS does not currently seem to properly test multiplicity of inputs.

Expected behavior
The ETS should use the array form for inputs with multiplicity > 1, and if minOccurs is < 2, it should also test the singular form (without the extra brackets).

Additional context
In the sample Echo process, imagesInput has a minOccurs of 1 and a maxOccurs of 150.
The ETS should test various forms e.g.:

• "imagesInput" : [ "<base64 TIFF image1>", "<base64 TIFF image2>" ]
• "imagesInput" : "<base64 TIFF image1>"
• "imagesInput" : { "value": "<base64 TIFF image1>", "format": { "encoding": "base64", "mediaType": "image/tiff; application=geotiff" } }
• "imagesInput" : [ { "href": "http://example.com/image1.tiff" }, { "href": "http://example.com/image2.tiff", "type": "image/tiff; application=geotiff" } ]
• "imagesInput" : { "href": "http://example.com/image1.tiff" }
• "imagesInput" : [ { "href": "http://example.com/image1.tiff" }, "<base64 TIFF image2>" ]
• "imagesInput" : [ ] (error: less than minOccurs)
• "imagesInput" : null (or input missing; error: less than minOccurs)

This issue will be discussed at the SWG meeting on October 16th.

As there is currently no requirement for testing input multiplicity, we will leave this as open as enhancement for future work.
