Attributes

QName Type Fixed Default Use Inheritable Annotation
ana restriction of list of xs:anyURI optional 
(analysis) indicates one or more elements containing interpretations of
the element on which the ana attribute appears.
arity xs:nonNegativeInteger optional

change restriction of list of xs:anyURI optional 
points to one or more change elements documenting a state or revision

content of the element.
n xs:string optional 
(number) gives a number (or other label) for an element, which is not
necessarily unique within the document.
next xs:anyURI optional 
points to the next element of a virtual aggregate of which the current
element is part.
ord restriction of xs:token required 
(ordered) indicates whether or not the tree is ordered, or if it is
partially ordered.
order xs:nonNegativeInteger optional 
gives the order of the tree, i.e., the number of its
nodes.
prev xs:anyURI optional 
(previous) points to the previous element of a virtual aggregate of which
the current element is part.
rend restriction of list of restriction of xs:token optional 
(rendition) indicates how the element in question was rendered or

points to a description of the rendering or presentation used for this
element in the source text.
resp restriction of list of xs:anyURI optional 
(responsible party) indicates the agency responsible for the intervention
or interpretation, for example an editor or transcriber.
sameAs xs:anyURI optional 
points to an element that is the same as the current
element.
select restriction of list of xs:anyURI optional 
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.
style xs:string optional 
contains an expression in some formal style definition language which
defines the rendering or presentation used for this element in the source
text
synch restriction of list of xs:anyURI optional 
(synchronous) points to elements that are synchronous with the current
element.
xml:base xs:anyURI optional 
provides a base URI reference with which applications can resolve relative URI references into absolute URI references.
xml:id xs:ID optional 
(identifier) provides a unique identifier for the element bearing the attribute.
xml:lang union of(xs:language, restriction of xs:token) optional 
(language) indicates the language of the element content using a tag generated according to BCP 47.
