Represents the "Name" entry of the optional content usage user dictionary object.

It is a required entry defined as part of the PDF 1.0 specification.

It contains an array which contains strings, representing PDF string objects.

If you read the specification you will see that an array of one string may be represented as a single string rather than an array. However we always present this property as an array to simplify the interface. It is only if you add or remove items in the array, that the underlying representation will be changed.

The Name entry holds the identifier of the target user or user group. It may be a single string or an array of strings when multiple users or groups are targeted. Applications compare this against the current user's identity when deciding whether to show the content.
