<tree> (tree) codifica un albero, che è costituito da radice, nodi interni, foglie, e archi che collegano radice e foglie [19.2 Trees]

Attributiatt.global (@xml:id, @n, @xml:lang, @xml:base, @xml:space) (att.global.rendition (@rend, @style, @rendition)) (att.global.linking (@corresp, @synch, @sameAs, @copyOf, @next, @prev, @exclude, @select)) (att.global.analytic (@ana)) (att.global.facs (@facs)) (att.global.change (@change)) (att.global.responsibility (@cert, @resp)) (att.global.source (@source))
aritystabilisce il numero massimo di figli della radice e dei nodi interni dell'albero
Stato Opzionale
Tipo di dati teidata.count
ord(ordinato) indica se l'albero è ordinato o parzialmente ordinato
Stato Richiesto
Tipo di dati teidata.enumerated
I valori legali sono:
true
indica che tutti i nodi ramo dell'albero sono ordinati
partial
indica che alcuni dei nodi ramo dell'albero sono ordinati e che altri non lo sono
false
indica che tutti i nodi ramo dell'albero non sono ordinati
orderindica l'ordine dell'albero, cioè il numero dei suoi nodi
Stato Opzionale
Tipo di dati teidata.count

Nota

A root, and zero or more internal nodes and leaves, but if there is an internal node, there must also be at least one leaf.
