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.
See literal property

Applicability: all presentation elements

common

Effect: Assistive technology should use the specified common defaults.
See common property

Applicability: all presentation elements

legacy

Effect: Assistive technology should use its system specified defaults. This is the default behavior if neither theliteral propertynorcommon propertyis in effect. See legacy property

Applicability: all presentation elements

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

Applicability: mtable

equation-label

Effect: indicates that the cell holds an equation label. This may influence the way the surrounding mtr is announced.

Applicability: mtd

no-equation-label

Effect: indicates that the cell does not hold a label. This may be used if a table column is being used solely to hold labels to highlight empty cells for unlabeled rows.

Applicability: mtd
