+## is_authority Integration
+Other programs can check if a verification method (e.g. public key or address) by integrating `is_authority`:
+
+```rust
+use sol_did::integrations::is_authority;
+```
+
+```rust
+// pub fn is_authority(did_account: &AccountInfo, 
+//                     did_account_seed_bump: Option<u8>, 
+//                     controlling_did_accounts: &[AccountInfo],

+//                     filter_fragment: Option<&String>) -> Result<bool>
