+# Conformance # {#conformance}
+
+The iLEAP Technical Specifications are designed to be incrementally adopted and
+realized in [=host systems=] for different stakeholder groups. Therefore,
+there are 2 kinds of <dfn>iLEAP conformance</dfn> defined:
+
+1. [=iLEAP Emissions Data Conformance=]
+1. [=iLEAP Activity Data Conformance=]
+
+For each kind of iLEAP Conformance, a host system achieves conformity by
+
+1. realizing the normative statements and relevant test cases referenced
+    in [[#ileap-conformance-matrix]] below,
+2. successfully passing Bilateral Testing ([[#conformity-bilateral-testing]])
+3. succesfully passing the [Automated Conformance Testing](https://act.sine.dev)
+
+To achieve iLEAP Emissions Data Conformance, [=host systems=] are further REQUIRED to support the
+following features:
+1. fetching <{TAD}> from another host system and
+2. using it to generate <{TOC}>, <{HOC}>, or <{ShipmentFootprint}> data.
+
+It is RECOMMENDED for host systems to conform to both kinds of [=iLEAP conformance=].
+
+Sections marked as non-normative, all authoring guidelines, diagrams, examples,
+and notes in this specification are non-normative. Everything else in this
+specification is normative.
+
+The key words MAY, MUST, MUST NOT, OPTIONAL, RECOMMENDED, REQUIRED, SHOULD,
+and SHOULD NOT in this document are to be interpreted as described in
+[[!RFC2119]] [[!RFC8174]] when, and only when, they appear in all capitals,
+as shown here.
+
+Advisement: Currently, iLEAP Conformance ensures interoperability and syntactic correctness. Future
+updates will extend coverage to include semantic correctness, ensuring that emissions calculations
+are performed accurately in end-to-end scenarios.

+## Bilateral Testing ## {#conformity-bilateral-testing}
+
+A Bilateral Test is an interoperability test where two different [=host system=]
+implementations participate to verify conformance ([[#conformance]]) and their
+ability to work together.
+
+One system acts as the [=data owner=]. It is called the <dfn>target host system</dfn> and is the system under test.
+The second system acts as the testing party.
+
+Note:
+  The objective of Bilateral Testing is to ensure that systems can effectively
+  communicate despite having independent codebases.
+
+
+## Submission ## {#conformity-submission}
+
+Note: non-normative
+
+Once a [=host system=] achieved [=iLEAP conformance=] in 1 or all kinds of iLEAP conformance,
+the implementer is requested to reach out to the authors of this Technical Specifications to
+apply for additional support, materials, and marketing opportunities.
