Notes

Bugs

  • This parser does not handle resource types. Handling resource types is 

    subtle: they may be separated from resource IDs by a colon OR by a slash. For an
example of a resource type, see ECS[1] (uses only slash separators). That colons
are an acceptable separator appears in [2], so a workaround to this limitation is
to use a slash.
