Properties
Fixity
function
Effect : the function head is voiced followed by a connector such as "of" or "applied" to, followed by the arguments separated by connecting words such as "comma" or "and"
Applicability : intent function head
f:function(x,y)
English:
f of x comma y
English:
f of x and y
French:
f de x et y
prefix
Effect : the function followed by the arguments are voiced, with no connecting words.
Applicability : intent function head
f:prefix(x,y)
English:
f x y
postfix
Effect : the arguments followed by the function are voiced, with no connecting words.
Applicability : intent function head
f:postfix(x)
English:
x f
infix
Effect : the arguments are voiced, separated by the function, which may be repeated if there are more than two arguments.
Applicability : intent function head
f:infix(x,y)
English:
x f y
silent
Effect : the arguments are voiced with no connecting words. The function head is not read.
Applicability : intent function head
f:silent(x,y)
English:
x y
Inference
literal
Effect : Assistive technology should not infer any semantics and just speak the elements with a literal interpretation. This includes speaking leaf content literally (e.g., `|` is spoken as "vertical bar"). If `intent` is present on a child element, it overrides this property.
Applicability : all presentation elements
<mrow intent= ':literal' >
<msup intent= 'power($base, $exp)' > <mi arg= 'base' > x</mi><mn arg= 'exp' > 2</mn> </msup>
<mtext> is literally </mtext>
<msup> <mi> x</mi><mn> 2</mn> </msup>
</mrow>
x 2
is literally
x 2
English:
x squared is literally x superscript 2 end superscript
Table
array
Effect : the table should read the rows and columns with the default order row-first unless `array:by-column` is specified. If `by-columns` is used, column first order is used.
Applicability : mtable
:array:by-columns
<mtable arg= 'm' intent= ':array:by-column' >

f ( x )
=
{
− x
if
x < 0
x
if
x ≥ 0
English:
f of x is equal to; 3 cases, case 1; negative 1 if x; is less than 0; case 2; 0 if x, is equal to 0; case 3; 1 if x, is greater than 0;
system-of-equations
Effect : the table should be read in a style suitable for displayed equations (and inequations)
Applicability : mtable

1
y
>
x − 3
English:

Applicability : mtr
by-row
Effect : indicates that the table should be read row by row
