Question: Which specification(s) primarily define the toolkit features utilized within the `uicc.usim.toolkit` package of the (U)SIM toolkit API?
Option 1: ETSI TS 102 241 alone
Option 2: Only TS 31.111 and TS 51.014 jointly
Option 3: Solely based on 3GPP TS 31.130
Option 4: Both TS 31.111 and TS 51.014, in conjunction with the foundational aspects from ETSI TS 102 241
Explanation: The (U)SIM toolkit API's `uicc.usim.toolkit` package draws its toolkit features from TS 31.111 for USIM Application Toolkit and TS 51.014 for SIM Application Toolkit, building upon the foundational `uicc.toolkit` package defined in ETSI TS 102 241, combining USIM-specific and broader SIM toolkit functionalities.
