As specified in Specializations section the MDC code for a generic specialization is 8::4169 which gives us the code 528457 after conversion. The 528457 code is used in the referenced example.
However, the code 528385 is given as example in the text of the specification:

{{specialization.systemType.coding.code=”528385”
specialization.systemType.coding.system=”urn.iso.std.iso:11073:10101”
specialization.systemType.text=”MDC_DEV_SPEC_PROFILE_GENERIC: supports all 20601 devices”
specialization.version=”2”}}

Any reason explaining this difference or is it a typo?
