Update the existing table in section 4.11.8 as follows:   Change the 3rd column heading to DependsOn.value Update the text (below the table) in 4.11.8  http://build.fhir.org/conceptmap2.html#dependencies From: When attempting to translate the source to the target, an application must also provide a value for the element identified in  dependsOn.property  so that the correct mapping can be performed. To support the reverse operation,  product  is the converse, and works in reverse. TO: When attempting to translate the source to the target, an application SHOULD also provide a value for the element identified in  dependsOn.property  so that the correct mapping can be performed.  All dependsOn and product values are included in the output of $translate. Update the definition of element dependsOn.property to :    Short definition: A reference to a property that may be required to refine the mapping.  Long definition:   Current:  A reference to an element that holds a coded value that corresponds to a code system property. The idea is that the information model carries an element somewhere that is labeled to correspond with a code system property. Change to: A reference to a property that holds a value the map depends on. This value can be supplied to the $translate operation to select the appropriate targets.
