Issue with correctly processing regex value in value set filter #186

The expansion of the value set Iso 3166 Part 1: 2 Letter Codes from the core FHIR specification has the following compose element:

Which is intended to include all concept where the code value is 2-characters long.

However, the expansion generated by tx.fhir.org is also including the concepts that have 3-character codes. See here

This suggests that the "[A-D]{2}" regular expression is not being correctly processed by the server.
