+
+Summary may be available to the instrumentation through

+Parameterized query text SHOULD NOT be sanitized.

+Absolute URL describing a network resource according to [RFC3986](https://www.rfc-editor.org/rfc/rfc3986).
+Note: For network calls, URL usually has `scheme://host[:port][path][?query][#fragment]` format, where the fragment
+is not transmitted over HTTP, but if it is known, it SHOULD be included nevertheless.
+
+`url.full` MUST NOT contain credentials passed via URL in form of `https://username:password@www.example.com/`.
+In such case username and password SHOULD be redacted and attribute's value SHOULD be `https://REDACTED:REDACTED@www.example.com/`.
+
+`url.full` SHOULD capture the absolute URL when it is available (or can be reconstructed).
+
+Sensitive content provided in `url.full` SHOULD be scrubbed when instrumentations can identify it.
