Converting Arrays to Attribute Strings

which produces the following result:

We can use $$ to escape the beginning of a variable string to emit string beginning with a single $:
which produces the following output:
Attribute Renderer does not support more complicated variable paths, such as nested properties, or array indices. If you need something more complicated, consider using a closure based variable resolver.

produces:
we can let Attribute Renderer know its okay to ignore a property when producing the final result:
would now produce:
