|Metadata, conditional processing, and indexing / Condition (or select) attributes|
By using a convention for recording values in the otherprops attribute, you can extend the amount of metadata stored.
The otherprops attribute can be used for storing any other metadata information that does not otherwise fit into the standard condition attributes (audience, platform, and product).
To extend the functionality of the otherprops attribute, a naming convention can be used that a processor can interpret and action. For example, settings of otherprops="Market(Australia)" and otherprops="Publication(Symmetry)" would allow the same attribute to be used for a number of functions. In this example, a processor could differentiate between "Market" and "Publication".
