Text that is provided for display, generally in lieu of an image.

This attribute is used to identify content that is intended for a particular audience.

During the digital production process for ldsXML there was style information added downstream. During the schemas development the working group has explicitly chosen not to add style information to the content, instead they are relying on semantic based values. This attribute will temporarily store those values. The reason for doing this it keep these values close at hand for a season just in case we need it during the migration period. It is intended to be deprecated from the content and the schema as soon as it is prudent.

During the migration of content from ldsXML to (x)HTML5 we sometimes had both a mediaID and a webURL on an image tag, when this happened we have chosen to use the mediaID as the value for the @src and we stored the webURL in this attribute. The reason for doing this it keep this value close at hand for a season just in case we need it during the migration period. It is intended to be deprecated from the content and the schema as soon as it is prudent.

For use in notifying downstream publishing channels if there is content that is specific for their channel.

This attribute represents a graduated range of values forming a standard system for measuring or grading the element that it is assigned to.

"property-name" — adds a property to a microdata item. The name of the property can be a word or URL, and the value is the ‘content’ of the element with this attribute.

Defines a group of name-value pair(s), called an item

defines the item’s type when used on the same element as itemscope. The itemtype value is a URL that acts as an identifying vocabulary name.

The src attribute must contain a valid non-empty URL potentially surrounded by spaces referencing a non-interactive, optionally animated, image resource that is neither paged nor scripted.
