The <<introduction-conventions>> section of the 49<<introduction>> defines how these parts of the Specification are identified. 50 51Where this Specification uses <<introduction-technical-terminology,technical 52terminology>>, defined in the <<glossary, Glossary>> or otherwise, that 53refer to enabling technologies that are not expressly set 54forth in this Specification, those enabling technologies are EXCLUDED from 55the Scope of this Specification. For clarity, enabling technologies not 56disclosed with particularity in this Specification (e.g. semiconductor 57manufacturing technology, hardware architecture, processor architecture or 58microarchitecture, memory architecture, compiler technology, object oriented 59technology, basic operating system technology, compression technology, 60algorithms, and so on) are NOT to be considered expressly set forth; only 61those application program interfaces and data structures disclosed with 62particularity are included in the Scope of this Specification. 63 64For purposes of the Khronos Intellectual Property Rights Policy as it 65relates to the definition of Necessary Patent Claims, all recommended or 66optional features, behaviors and functionality set forth in this 67Specification, if implemented, are considered to be included as Compliant 68Portions. 69 70// End "Normative Wording" section 71 72// "External References" section 73 74Where this Specification identifies specific sections of external 75references, only those specifically identified sections define 76<<introduction-normative-references, normative>> 77functionality. The Khronos Intellectual Property Rights Policy excludes 78external references to materials and associated enabling technology not 79created by Khronos from the Scope of this specification, and any licenses 80that may be required to implement such referenced materials and associated 81technologies must be obtained separately and may involve royalty payments. 82 83// End "External References" section 84 85ifndef::ratified_core_spec[] 86This document contains extensions which are not ratified by Khronos, and as 87such is not a ratified Specification, though it contains text from (and is a 88superset of) the ratified Vulkan Specification.
