> In Funding Circle we use avro schema to validate some financial data and 
> we've found ourselves wondering what is invalid. We've noticed that avro 
> [does already 
> validation|https://github.com/apache/avro/blob/master/lang/ruby/lib/avro/schema.rb#L94],
>  but does not report what fields are invalid, so we've decided to change it 
> and we use Avro as a validation library.
> h5. What error messages to expect?
> We communicate errors for a given payload in format "at <path> <expected> 
> <received>".
> For <path> we've decided to use syntax similar to json path:
> * . refers to root
> * \[0\] first index in array
> * .age would match 42 from {"age": 42}
> Error within object *person* and his optional array *houses* on *second item* 
> with key *number_of_rooms*:
> {quote}
>     at .person.houses\[1\].number_of_rooms expected type long, got string 
> with value "not valid at all"
> {quote}
> Example of multiple errors for a single payload:
> {quote}
>     at .\[0\] expected type int, got null
>     at .\[1\] expected type int, got string with value \"e\"
> {quote}
> More examples can be seen at
