<metDecl>

<metDecl> 在標記韻文時所用到的結構性元素 (例如lgl、或seg) 當中,若使用metreal、或rhyme等屬性的屬性值來表示文章的韻律模式,則在此宣告標記韻律模式的方法。 [6.5 Metrical Notation Declaration 6.3 Rhyme and Metrical Analysis]
組件verse — 6 Verse
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.declarable (@default)
type指出該標記所傳達的為抽象韻律形式、實際韻律實踐、或者押韻形式,或任幾項之結合。
狀態 非必備的
資料類型 1–3 次可出現: 

<rng:ref name="data.enumerated"/>
data.enumerated
以空白鍵隔開
合法的值是:
met
(屬性met 屬性rhyme ) 屬性 met宣告適用於該屬性所紀錄的抽象韻律形式。屬性rhyme宣告適用於該屬性所紀錄的押韻形式
real
(屬性real ) 屬性real宣告適用於該屬性所紀錄的通用韻律結構之實際實踐
rhyme
(rhyme attribute) declaration applies to the rhyme scheme recorded on the rhyme attribute
pattern (regular expression pattern) 標明一種固定表示法,用來定義任何合用於此標記的屬性值。
狀態 非必備的
資料類型

<rng:ref name="data.pattern"/>
data.pattern
the value must be a valid regular expression per the World Wide Web Consortium's XML Schema Part 2: Datatypes Second Edition, Appendix F
