   PioPath provides a simplistic DSL for working with the OCS3 export format for OCS2 data.

   PioPath provides a simplistic DSL for working with the OCS3 export format for OCS2 data. The language consists of an operator:

   • \! - required element
   • \? - optional element
   • \* - list of immediate child elements
   • \\* - list of descendent elements

   and a corresponding match string where the initial character is:

   • '@' - attribute element
   • '#' - param element with the given name
   • '&' - paramset element with the given name
   • - (i.e., no special character) child element

   Example:

   (n \?  "instrument" \! "@type")

   Node with an optional <instrument> element that, if it exists, has a required "type" attribute. When decoded, any path that included a ? but not a * will produce an Option result. Any path including a * will produce a List.

   If a required element is missing, the result will be MissingKey PioError when decoded.
