Topic: Specify a specific extension or slice in a 'path' attribute
Travis Stenerson (Nov 23 2017 at 15:26):
How does one specify a specific extension in a path element? I suppose this is also asking how does one specify a particular slice in a path element, such as those found in Definitional resources.
Here's an example: My medication request resource has two extensions, one of which has the uri "http://baseURL/line-of-therapy" and is a CodeableConcept. How would I specify the path to this extension in 'dataRequirement.mustSupport', 'dataRequirement.codeFilter.path', or in '_Definition.dynamicValue.path'?
Thank you

The FHIRPath specification defines additional operators for working with FHIR that allow you to reference extensions and slices, .extension() and .slice(). So for the extension, the path would be .extension('http://baseURL/line-of-therapy'), and similarly for the slice, the path would be .extension('http://baseURL/example-sd', 'slice-name').
