D.5 Voci del dizionario
degli operatori
La tabella seguente dà il dizionario consigliato delle
proprietà di riproduzione per operatori, parentesi, separatori
e accenti in MathML, i quali sono tutti rappresentati da elementi
mo
. Per brevità, tutti questi elementi saranno
chiamati semplicemente `operatori' in questa Appendice.
Gli operatori sono divisi in gruppi, che sono separati da linee
bianche nell'elenco seguente. Il raggruppamento, e l'ordine dei
gruppi, è significativo per il corretto raggruppamento delle
sottoespressioni usando <mrow>
(Sezione 3.3.1 [Raggruppare
orizzontalmente le sottoespressioni (mrow
)]); la
regola descritta qui è particolarmente rilevante per la
generazione automatica del MathML per conversione da altri formati per
la matematica visualizzata, come TEX, che non sempre
specificano come si annidano le sottoespressioni.
Il formato delle voci della tabella è: il contenuto
dell'elemento <mo>
tra doppi apici (tag di apertura
e di chiusura non mostrati), seguito dalla lista degli attributi in
formato XML, iniziando con l'attributo form
, seguito
dagli attributi predefiniti di riproduzione che devono essere usati
per elementi mo
con il dato contenuto e il dato attributo
form
.
Ogni attributo non elencato per una voce ha il suo valore
predefinito, che è dato tra parentesi nella tabella degli
attributi nella Sezione 3.2.4
[Operatore, parentesi, separatore o accento (mo
)].
Si noti che i caratteri & e < sono rappresentati nelle
seguenti voci di tabella rispettivamente dai riferimenti ad
entità &
e <
, come
sarebbe necessario se apparissero nel contenuto di un elemento
mo
reale (o in qualunque altro elemento MathML o XML).
Per esempio, la prima voce,
"(" form="prefix" fence="true" stretchy="true" lspace="0em" rspace="0em"
potrebbe essere espressa come elemento mo
da:
<mo form="prefix" fence="true" stretchy="true" lspace="0em" rspace="0em"> ( </mo>
(si noti la mancanza di doppi apici intorno al contenuto, e gli spazi bianchi aggiunti intorno al contenuto per leggibilità, cosa opzionale nel MathML).
Questa voce significa che, per riproduttori MathML che usano questo
dizionario degli operatori consigliato, dare l'elemento <mo
form="prefix"> ( </mo>
da solo, o
semplicemente <mo> ( </mo>
in una posizione
per la quale sarebbe inferito form="prefix"
(si
veda sotto), è equivalente a dare l'elemento con tutti gli
attributi mostrati sopra.
Si noti che il dizionario è indicizzato non solo a seconda
del contenuto degli elementi, ma a seconda del contenuto degli
elementi e del valore dell'attributo form
, insieme. Gli
operatori con più di una forma possibile hanno più di
una voce. Le specifiche del MathML descrivono come il riproduttore
sceglie (`inferisce') quale forma usare quando non è dato un
attributo form
; si veda la Sezione 3.2.4.7.2. [Valore
predefinito dell'attributo form
].
Avendo fatto questa scelta, o con l'attributo form
specificato esplicitamente nel tag iniziale dell'elemento
<mo>
, il riproduttore MathML usa gli attributi
rimanenti dalla voce del dizionario per la sola forma appropriata di
tale operatore, ignorando le voci per altre forme possibili.
I caratteri estesi in MathML (e nel dizionario degli operatori in
seguito) sono rappresentati da riferimenti ad entità in stile
XML usando la sintassi &nome-del-carattere;
, l'elenco
completo dei caratteri e dei nomi dei caratteri è dato nel Capitolo 6 [Caratteri, entità e
font]. A molti caratteri si può fare riferimento con
più di un nome; spesso, in MathML sono forniti nomi facili da
ricordare composti da parole intere, come pure uno o più nomi
usati in altri standard, come l'Unicode. I caratteri negli operatori
in questo dizionario sono elencati generalmente sotto il loro nome a
parole intere, quando esiste. Per esempio, l'operatore integrale
è chiamato in seguito con la sequenza di un carattere
∫
, ma potrebbe altrettanto bene essere
chiamato ∫
. La scelta di un nome per un dato
carattere in MathML non ha effetto sulla sua presentazione.
Si intende che ogni entità nominata in seguito appare da qualche parte nel Capitolo 6 [Caratteri, entità e font]. Se questo non è vero, è un errore in queste specifiche. Se tale errore esiste, deve essere considerato come definitivo il capitolo sopra nominato, piuttosto che questa appendice.
lspace
e rspace
I valori per lspace
e rspace
dati qui
variano da 0 a verythickmathspace
, che ha un valore
predefinito di 6/18 em. Per gli operatori invisibili il cui contenuto
è ⁢
o
⁡
, si consiglia che i riproduttori
MathML scelgano la spaziatura in un modo dipendente dal contesto (che
è un'eccezione ai valori statici dati nella seguente tabella).
Per <mo>⁡</mo>
, la
spaziatura totale (lspace
+rspace
) in
espressioni come `sin x' (dove l'operando a destra non inizia
con una parentesi) deve essere maggiore di zero; per
<mo>⁢</mo>
, la spaziatura
totale deve essere maggiore di zero quando entrambi gli operandi (o i
token più vicini da ogni lato, se sulla linea di base) sono
identificatori visualizzati in un font non inclinato (ovvero, sotto le
regole consigliate, quando entrambi gli operandi sono identificatori
multi-carattere).
Alcuni riproduttori possono non voler usare nessuna spaziatura per
la maggior parte degli operatori che appaiono negli apici e nei pedici
(ovvero quando scriptlevel
è maggiore di 0; si
veda la Sezione 3.3.4
[Modifiche allo stile (mstyle
)]), come è il
caso in TEX.
