(corresponds) points to elements that correspond to the current element in some way. (synchronous) points to elements that are synchronous with the current element. points to an element that is the same as the current element. points to an element of which the current element is a copy. points to the next element of a virtual aggregate of which the current element is part. (previous) points to the previous element of a virtual aggregate of which the current element is part. points to elements that are in exclusive alternation with the current element. selects one or more alternants; if one alternant is selected, the ambiguity or uncertainty is marked as resolved. If more than one alternant is selected, the degree of ambiguity or uncertainty is marked as reduced by the number of alternants not selected. categorizes the pointer in some respect, using any convenient set of categories. specifies the intended meaning when the target of a pointer is itself a pointer. all if the element pointed to is itself a pointer, then the target of that pointer will be taken, and so on, until an element is found which is not a pointer. one if the element pointed to is itself a pointer, then its target (whether a pointer or not) is taken as the target of this pointer. none no further evaluation of targets is carried out beyond that needed to find the element specified in the pointer's target. optionally specifies the identifiers of the elements within which all elements indicated by the contents of this element lie. (target function) describes the function of each of the values of the targets attribute of the enclosed link, join, or alt tags. (anonymous block) contains any arbitrary component-level unit of text, acting as an anonymous container for phrase or inter level elements analogous to, but without the semantic baggage of, a paragraph. specifies whether or not the block is complete. Y (yes) the block is incomplete N (no) either the block is complete, or no claim is made as to its completeness I (initial) the initial part of an incomplete block M (medial) a medial part of an incomplete block F (final) the final part of an incomplete block (alternation) identifies an alternation or a set of choices among elements or passages. specifies the identifiers of the alternative elements or passages. states whether the alternations gathered in this collection are exclusive or inclusive. excl (exclusive) indicates that the alternation is exclusive, i.e. that at most one of the alternatives occurs. incl (inclusive) indicates that the alternation is not exclusive, i.e. that one or more of the alternatives occur. If mode is , each weight states the probability that the corresponding alternative occurs. If mode is incl each weight states the probability that the corresponding alternative occurs given that at least one of the other alternatives occurs. (alternation group) groups a collection of alt elements and possibly pointers. states whether the alternations gathered in this collection are exclusive or inclusive. excl (exclusive) indicates that the alternation is exclusive, i.e. that at most one of the alternatives occurs. incl (inclusive) indicates that the alternation is not exclusive, i.e. that one or more of the alternatives occur. (anchor point) attaches an identifier to a point within a text, whether or not it corresponds with a textual element. identifies a possibly fragmented segment of text, by pointing at the possibly discontiguous elements which compose it. specifies the identifiers of the elements or passages to be joined into a virtual element. specifies the name of an element which this aggregation may be understood to represent. indicates whether the targets to be joined include the entire element indicated (the entire subtree including its root), or just the children of the target (the branches of the subtree). root the rooted subtrees indicated by the targets attribute are joined, each subtree become a child of the virtual element created by the join branches the children of the subtrees indicated by the targets attribute become the children of the virtual element (i.e. the roots of the subtrees are discarded) (join group) groups a collection of join elements and possibly pointers. describes the result of the joins gathered in this collection. defines an association or hypertextual link among elements or passages, of some type not more precisely specifiable by other elements. specifies the identifiers of the elements or passages to be linked or associated. (link group) defines a collection of associations or hypertextual links. (arbitrary segment) represents any segmentation of text below the chunk level. (timeline) provides a set of ordered points in time which can be linked to elements of a spoken text to create a temporal alignment of that text. designates the origin of the timeline, i.e. the time at which it begins. specifies the unit of time corresponding to the interval value of the timeline or of its constituent points in time. Suggested values include: 1] d (days); 2] h (hours); 3] min (minutes); 4] s (seconds); 5] ms (milliseconds) d (days) h (hours) min (minutes) s (seconds) ms (milliseconds) specifies the numeric portion of a time interval 0 regular irregular indicates a point in time either relative to other elements in the same timeline tag, or absolutely. supplies an absolute value for the time. specifies the unit of time in which the interval value is expressed, if this is not inherited from the parent timeline. Suggested values include: 1] d (days); 2] h (hours); 3] min (minutes); 4] s (seconds); 5] ms (milliseconds) d (days) h (hours) min (minutes) s (seconds) ms (milliseconds) specifies the numeric portion of a time interval 0 unknown identifies the reference point for determining the time of the current when element, which is obtained by adding the interval to the time of the reference point.
