<classSpec>

<classSpec> 包含一個TEI元素集的參照資訊；元素集是一群在內容模組中同時出現、或共用某些屬性、或兩者皆包括的元素。 [22.3 Specification Elements 22.4.6 Element Classes]
組件tagdocs — Documentation Elements
屬性att.global (@xml:id, @n, @xml:lang, @rend, @style, @rendition, @xml:base, @xml:space) (att.global.linking (@corresp, @synch, @sameAs, @copyOf, @next, @prev, @exclude, @select)) (att.global.analytic (@ana)) (att.global.facs (@facs)) (att.global.change (@change)) att.identified (@ident, @predeclare, @module, @status) (att.combinable (@mode) (att.deprecated (@validUntil)) )
type指出這是結構元素集或是屬性元素集。
狀態 必備的
資料類型 

<rng:ref name="data.enumerated"/>
data.enumerated
合法的值是:
model
(content model) 該元素集的元素出現在相同的內容模組中
atts
(attributes) 該元素集的元素有共用的屬性
generate說明應該建立結構元素集的哪些替換及順序作業實例。在預設的情形下，會提供所有的變數。
狀態 非必備的
資料類型 1–5 次可出現: 

<rng:ref name="data.enumerated"/>
data.enumerated
以空白鍵隔開
合法的值是:
alternation
該元素集的元素是替換元素
sequence
該元素集的元素會依序呈現
sequenceOptional
該元素集的元素可依序呈現，但非必須
sequenceOptionalRepeatable
該元素集的元素可一次或多次依序呈現，但非必須
sequenceRepeatable
該元素集的元素可一次或多次依序呈現
