<metDecl>   (metrical notation declaration) documents the notation employed to represent a metrical pattern when this is specified as
    the value of a met , real , or rhyme  attribute on any structural
    element of a metrical text (e.g. lg , l , or seg ). 6.5  Metrical Notation Declaration6.3  Rhyme and Metrical Analysis組件 verse — 6  Verse 屬性 att.global  (@xml:id , @n , @xml:lang , @rend , @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 indicates whether the notation conveys the abstract metrical form, its actual prosodic
        realization, or the rhyme scheme, or some combination thereof.狀態  非必備的 資料類型   1–3 次可出現:  以空白鍵隔開  合法的值是: met  (met attribute) declaration applies to the abstract metrical form recorded on the met 
            attribute real  (real attribute) declaration applies to the actual realization of the conventional metrical structure
            recorded on the real  attribute rhyme  (rhyme attribute) declaration applies to the rhyme scheme recorded on the rhyme  attribute 
 pattern  (regular expression pattern) specifies a regular expression defining any value that is legal for this notation.狀態  非必備的 資料類型  值  the value must be a valid regular expression per the World Wide Web Consortium's

    <metDecl xml:id="ip " type="met " pattern="((SU|US)USUSUSUS/) ">  <metSym value="S "> stressed syllable
</metSym>  <metSym value="U "> unstressed syllable
</metSym>  <metSym value="/ "> metrical line boundary
</metSym> </metDecl> This example is intended for the far more restricted case typified by the Shakespearean
      iambic pentameter. Only metrical patterns containing exactly ten syllables, alternately
      stressed and unstressed, (except for the first two which may be in either order) to each
      metrical line can be expressed using this notation.
