An Istio attribute carries a specific piece of information about an activity,
such as the error code of an API request, the latency of an API request, or the
original IP address of a TCP connection. The attributes are often generated
and consumed by different services. For example, a frontend service can
generate an authenticated user attribute and pass it to a backend service for
access control purpose.</p><p>To simplify the system and improve developer experience, Istio uses
shared attribute definitions across all components. For example, the same
authenticated user attribute will be used for logging, monitoring, analytics,
billing, access control, auditing. Many Istio components provide their
functionality by collecting, generating, and operating on attributes.
For example, the proxy collects the error code attribute, and the logging
stores it into a log.</p><h3 id=design>Design</h3><p>Each Istio attribute must conform to an <code>AttributeInfo</code> in an
<code>AttributeManifest</code> in the current Istio deployment at runtime. An
<em><code>AttributeInfo</code></em> is used to define an attribute&rsquo;s
metadata: the type of its value and a detailed description that explains
the semantics of the attribute type. Each attribute&rsquo;s name is globally unique;
in other words an attribute name can only appear once across all manifests.</p><p>The runtime presentation of an attribute is intentionally left out of this
specification, because passing attribute using JSON, XML, or Protocol Buffers
does not change the semantics of the attribute. Different implementations
can choose different representations based on their needs.</p><h3 id=http-mapping>HTTP Mapping</h3><p>Because many systems already have REST APIs, it makes sense to define a
standard HTTP mapping for Istio attributes that are compatible with typical
REST APIs. The design is to map one attribute to one HTTP header, the
attribute name and value becomes the HTTP header name and value. The actual
encoding scheme will be decided later.</p><table class=message-fields><thead><tr><th>Field</th><th>Type</th><th>Description</th><th>Required</th></tr></thead><tbody><tr id=AttributeManifest-AttributeInfo-description><td><code>description</code></td><td><code>string</code></td><td><p>A human-readable description of the attribute&rsquo;s purpose.</p></td><td>No</td></tr><tr id=AttributeManifest-AttributeInfo-value_type><td><code>valueType</code></td><td><code><a href=#ValueType>ValueType</a></code></td><td><p>The type of data carried by this attribute.</p></td><td>Yes</td></tr></tbody></table></section><h2 id=Authentication>Authentication</h2><section><p>Authentication allows the operator to specify the authentication of
