Based on my quick skimming of the document, this is what openpgp uses
asymmetric crypto for:

From that document, the definition of key-transport key is as follows:
10. Private key-transport key: Private key-transport keys are the private keys
of asymmetric (public) key pairs that are used to decrypt keys that have been
encrypted with the corresponding public key using a public-key algorithm.
Key-transport keys are usually used to establish keys (e.g., key-wrapping
keys, data-encryption keys or MAC keys) and, optionally, other keying material
(e.g., Initialization Vectors).
That usage (data-encryption keys) is exactly what gnupg uses to encrypt a
file. You can go through the document and see the rest of the policies,
whether or not they apply to gnupg as implemented, but at first glance, that
is the case.
