Detailed Description

This contains some static methods for validating XMP properties.

See XMPInfo and XMPReader classes.

Each of these functions take the same parameters * an info array which is a subset of the XMPInfo::items array * A value (passed as reference) to validate. This can be either a simple value or an array * A boolean to determine if this is validating a simple or complex values

It should be noted that when an array is being validated, typically the validation function is called once for each value, and then once at the end for the entire array.

These validation functions can also be used to modify the data. See the gps and flash one's for example.

&$val	Mixed current value to validate
$standalone	Boolean if this is a simple property or array

static XMPValidate::validateClosed	(	$	info,
		&$	val,
		$	standalone
	)		`[static]`

function to validate properties with a fixed number of allowed choices.

(closed choice)

Parameters:

$info	Array information about current property
&$val	Mixed current value to validate
$standalone	Boolean if this is a simple property or array

static XMPValidate::validateDate	(	$	info,
		&$	val,
		$	standalone
	)		`[static]`

function to validate date properties, and convert to (partial) Exif format.

Dates can be one of the following formats: YYYY YYYY-MM YYYY-MM-DD YYYY-MM-DDThh:mmTZD YYYY-MM-DDThh:mm:ssTZD YYYY-MM-DDThh:mm:ss.sTZD

Parameters:

$info	Array information about current property
&$val	Mixed current value to validate. Converts to TS_EXIF as a side-effect. in cases where there's only a partial date, it will give things like 2011:04.
$standalone	Boolean if this is a simple property or array

		$	standalone
	)		`[static]`

function to validate LangCode properties ( en-GB, etc )

This is just a naive check to make sure it somewhat looks like a lang code.
