allowedErrorInNumbers

number. Default value: 0. Maximum allowed numeric error when comparing numbers.

allowedErrorIsAbsolute

boolean. Default value: false. Whether allowedErrorInNumbers is interpreted as an absolute (rather than relative) tolerance.

caseInsensitiveMatch

boolean. Default value: false. Whether text comparisons ignore letter case.

expandOnCompare

boolean. Default value: false. Whether to expand math expressions before comparing.

includeErrorInNumberExponents

boolean. Default value: false. Whether the allowed numeric error also applies to numbers in exponents.

matchBlanks

boolean. Default value: false. Whether unfilled blanks in a math expression count as a match.

matchByExactPositions

boolean. Default value: false. Whether to match list values by exact position rather than by content.

numPeriodicSetMatchesRequired

integer. Default value: 3. Number of consecutive elements of a periodic set required to count as a match.

numSignErrorsMatched

number. Default value: 0. Maximum number of sign errors that still count as a match.

simplifyOnCompare

keyword. Level of simplification applied to math expressions before comparing.

Value	Description
`none` (default)	No simplification is applied before comparing.
`full`	Fully simplify both expressions before comparing.
`numbers`	Simplify numeric subexpressions only, leaving symbolic structure intact.
`numbersPreserveOrder`	Like `numbers`, but does not reorder commutative operands.
`normalizeOrder`	Reorder commutative operands into a canonical form without simplifying values.

symbolicEquality

boolean. Default value: false. Whether children compared via this boolean use symbolic equality.

unorderedCompare

boolean. Default value: false. Whether order is ignored when comparing list-like values.

disabled

boolean. Default value: false. Whether this component is disabled and cannot be interacted with.

extend

reference. Extend another component by reference, inheriting its children and attributes. Enter a reference as $name.

fixed

boolean. Default value: false. Whether this component's value is fixed and cannot be modified.

fixLocation

boolean. Default value: false. Whether this component's location is fixed (preventing it from being moved while still allowing other modifications).

hide

boolean. Default value: false. Whether to hide this component from the rendered output.

isResponse

boolean. Default value: false. Whether this component is treated as a response for the purposes of assessment.

name

text. The name used to reference this component from elsewhere in the document.

Examples

Example: `<or>` in a `<boolean>`

The <or> component functions as the boolean operator or, and checks to see whether any of the enclosed <boolean> references are true.

Example: `<or>` in an `<award>`

An <or> component is used to construct a compound boolean from three referenced <boolean> components within an <award>.
