Desired behavior

In internal code, I'm reviewing some failures that look like the following:

Error [Param.cc:354] Unknown error. Unable to set value [1.25 0.55 0.53 ] for key[pose]
...
Error: Error reading element <pose>
Error: Error reading element <visual>
Error: Error reading element <link>
Error: Error reading element <model>
Error: Error reading element <sdf>
Error: Unable to read file:<badly_formed_thing>.sdf

Sort of XPath-type hint, like /sdf/model[@name="blerg"]/link[@name="boo"]/visual[2]/pose

Alternatives considered

Split off from #479

Implementation suggestion

I had hacked something like this into urdf_parser_py: ros/urdf_parser_py#14
