(metrical structure, conventional) contains a user-specified encoding for the conventional metrical structure of the element. (metrical structure, realized) contains a user-specified encoding for the actual realization of the conventional metrical structure applicable to the element. (rhyme scheme) specifies the rhyme scheme applicable to a group of verse lines. (enjambement) indicates that the end of a verse line is marked by enjambement. Sample values include: 1] no; 2] yes; 3] weak; 4] strong marks the point at which a metrical line may be divided. (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). indicates whether the notation conveys the abstract metrical form, its actual prosodic realization, or the rhyme scheme, or some combination thereof. 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 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 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 (regular expression pattern) specifies a regular expression defining any value that is legal for this notation. (metrical notation symbol) documents the intended significance of a particular character or character sequence within a metrical notation, either explicitly or in terms of other symbol elements in the same metDecl. specifies the character or character sequence being documented. specifies whether the symbol is defined in terms of other symbols (terminal is set to false) or in prose (terminal is set to true). marks the rhyming part of a metrical line. provides a label to identify which part of a rhyme scheme this rhyming string instantiates.
