Synopsis
| f:select-mediaobject-data( | $data as element()*) as element()? |
| f:select-mediaobject-data( | $data as element()*, |
$force as xs:boolean) as element()? |
Description
Once a media object has been selected, one of its data elements
has to be selected. This function is responsible for making that
selection. It processes each of the data elements in
m:acceptable-mediaobject-data mode and returns the first
acceptable item.
If no acceptable items are found, the function will return the
empty sequence if $force is false. If $force
is true, the first data element will be returned, even though it was not
deemed “acceptable”.
