This document specifies raw() and addr() output script descriptors. raw() encapsulates a raw script as a descriptor. addr() encapsulates an address as a descriptor.

In order to make descriptors maximally compatible with scripts in use today, it is useful to be able to wrap any arbitrary output script or an address into a descriptor.
Two new script expressions are defined: raw() and addr().
The raw(HEX) expression can only be used as a top level descriptor. As the argument, it takes a hex string representing a Bitcoin script. The output script produced by this descriptor is the script represented by HEX.
The addr(ADDR) expression can only be used as a top level descriptor. It takes an address as its single argument. The output script produced by this descriptor is the output script produced by the address ADDR.
raw() and addr() descriptors use the format and general operation specified in 380. As this is a wholly new descriptor, it is not compatible with any implementation. The reuse of existing Bitcoin addresses allows for this to be more easily implemented.
raw() and addr descriptors have been implemented in Bitcoin Core since version 0.17.
