I think there is an issue with the generator not generating dynamodb.AttributeValues correctly. Looked at a few examples an noticed none of the nested structures were being generated. The example models include values though.

I didn't look at the other services to see if they had similar issues.

these comments still needed?

I noticed the buildComplex doesn't handle slices is that just because we didn't have any list data in example model?

would be helpful to document the isMap parameter and what its expectations are

I don't think this file should of changed.

I think these are missing nested values from the example model. Based on the description it sounds like there should be additional fields.

Key: map[string]*dynamodb.AttributeValue{

Should these have fields's AttributeValue have values?

I think something in the example generator is preventing AttributeValue fields from getting rendered. Or is these just missing from the model?
