Solution

I checked against the code that you have posted, and the issue is the code in the original post that you reference. There were some syntax mistakes in the xml that were trigging the error.

For any element that has a referenceBlock you can only include the name="" where in the original post i had an as and class. Removing those will clear up the issue. Remember to clear cache as the block xml is stored there if you are working with cache on.
