tstamp(optional)Encodes the onset time in terms of musical time, i.e., beats[.fractional beat part], as expressed in the written time signature. Value conforms to data.BEAT.
type(optional)Designation which characterizes the element in some sense, using any convenient classification scheme or typology that employs single-token labels. One or more values of datatype NMTOKEN, separated by spaces.
xlink:actuate(optional)Defines whether a link occurs automatically or must be requested by the user. Allowed values are: "onLoad" (Load the target resource(s) immediately.), "onRequest" (Load the target resource(s) upon user request.), "none" (Do not permit loading of the target resource(s).), "other" (Behavior other than allowed by the other values of this attribute.)
xlink:role(optional)Characterization of the relationship between resources. The value of the role attribute must be a URI. Value conforms to data.URI.
xlink:show(optional)Defines how a remote resource is rendered. Allowed values are: "new" (Open in a new window.), "replace" (Load the referenced resource in the same window.), "embed" (Embed the referenced resource at the point of the link.), "none" (Do not permit traversal to the referenced resource.), "other" (Behavior other than permitted by the other values of this attribute.)
xml:base(optional)Provides a base URI reference with which applications can resolve relative URI references into absolute URI references. Value conforms to data.URI.
xml:id(optional)Regularizes the naming of an element and thus facilitates building links between it and other resources. Each id attribute within a document must have a unique value. Value of datatype ID.
xml:lang(optional)Identifies the language of the element's content. The values for this attribute are language 'tags' as defined in BCP 47. All language tags that make use of private use sub-tags must be documented in a corresponding language element in the MEI header whose id attribute is the same as the language tag's value. Value of datatype language.
