Incorrect or misleading documentation about WOH conditional execution

The conditional execution documentation [1] seems to be wrong and/or misleading. Using parts of the described BFU cause:

2017-02-13 17:17:07,807 | ERROR | (BlueprintDeploymentListener:52) - Unable to parse deployed file /home/lars/dev/opencast/build/opencast-dist-allinone-2.4-SNAPSHOT/etc/workflows/fast-ng.xml
org.xml.sax.SAXParseException: The value of attribute "if" associated with an element type "operation" must not contain the '<' character.
