`public string`	# `getN( )` Retrieves string numeric magnitude. Retrieves string numeric magnitude. Returns `string`
`public string`	# `getUnit( )` Retrieves string unit. Retrieves string unit. Returns `string`
`public boolean`	# `isValid( )` Returns true if this length unit is valid. Returns true if this length unit is valid. Returns `boolean`
`public integer`	# `compareTo( HTMLPurifier_Length $l )` Compares two lengths, and returns 1 if greater, -1 if less and 0 if equal. Compares two lengths, and returns 1 if greater, -1 if less and 0 if equal. Parameters `$l` `HTMLPurifier_Length` $l Returns `integer` Warning If both values are too large or small, this calculation will not work properly
