These additional parameters can be specific values for the value, data, or other marker properties you specify. If the last marker with a particular key matches the other parameters you specify, the true open parameter is rendered and the marker is made available to the page through the marker output parameter.

Example
The following example shows how to determine if the last profile marker added to the current profile with a key of partner has a value of travel site A. Users who have such a marker see a message informing them about airfare discounts.
<dsp:droplet name="/atg/markers/userprofiling/droplet/ProfileHasLastMarkerWithKeyDroplet"> <dsp:param name="key" value="partner"/> <dsp:param name="value" value="travelSiteA"/> <dsp:param name="data" bean="ProfileHasMarkerWithKeyDroplet.ANY_VALUE"/> <dsp:oparam name="true"> When you book your hotel room with us, you'll receive a discount on airfare if you book your flight with travel site A! </dsp:oparam> </dsp:droplet>
