Constant value that identifies the attribute or characteristic in a language-independent way. Unique within the characteristic set.

In item-listing requests, if the ID is defined as -3 or -6 (Other) in GetAttributesCS or GetProductSellingPages, use ValueLiteral to specify the string value that the user entered. Otherwise, use ValueID to specify the ID that is pre-defined in GetAttributesCS or GetProductSellingPages. In item-listing requests and product searches, the possible ID values are:
-3 = User entered an arbitrary value (not an "Other" field)
-6 = User entered a value in an "Other" field
-100 = Value not specified (null)
#### (integer) = Identifier for a pre-defined value that the user selected (e.g., -14 or 1001)
For eBay.com, required if ValueList is specified. Not applicable to Half.com.

For Half.com, use AttributeArray.Attribute.Value.ValueLiteral in listing requests. For Half.com, AttributeArray.Attribute.Value.ValueLiteral is required when you use AddItem. See the eBay Web Services Guide for valid values. For the Half.com Notes attribute, the max length is 500 characters. You can revise AttributeArray.Attribute.Value.ValueLiteral for Half.com listings.
