The <<introduction-conventions>> section of 79the <<introduction>> defines how these parts of the Specification are 80identified. 81 82Where this Specification uses <<introduction-technical-terminology, 83technical terminology>>, defined in the <<glossary, Glossary>> or otherwise, 84that refer to enabling technologies that are not expressly set forth in this 85Specification, those enabling technologies are EXCLUDED from the Scope of 86this Specification. For clarity, enabling technologies not disclosed with 87particularity in this Specification (e.g. semiconductor manufacturing 88technology, hardware architecture, processor architecture or 89microarchitecture, memory architecture, compiler technology, object oriented 90technology, basic operating system technology, compression technology, 91algorithms, and so on) are NOT to be considered expressly set forth; only 92those application program interfaces and data structures disclosed with 93particularity are included in the Scope of this Specification. 94 95For purposes of the Khronos Intellectual Property Rights Policy as it 96relates to the definition of Necessary Patent Claims, all recommended or 97optional features, behaviors and functionality set forth in this 98Specification, if implemented, are considered to be included as Compliant 99Portions. 100 101// "Normative References" section 102 103Where this Specification identifies specific sections of external 104references, only those specifically identified sections define 105<<introduction-normative-references, normative>> 106functionality. The Khronos Intellectual Property Rights Policy excludes 107external references to materials and associated enabling technology not 108created by Khronos from the Scope of this Specification, and any licenses 109that may be required to implement such referenced materials and associated 110technologies must be obtained separately and may involve royalty payments. 111 112Khronos and Vulkan are registered trademarks, and SPIR-V is a trademark of 113The Khronos Group Inc.
