    The extension is unchanged in R4

    R3

    The extension is represented a little differently in R3:

    • Map the type url to uri on the element Extension.extension:value.value[x]
    • Map the type canonical to uri on the element Extension.extension:value.value[x]
    • Note: Extensions that have been modified for R3 are still draft while real-world experience is collected
