• <assign> – Assign a value to a property in the business process execution context.
• <branch> – Conditionally cause an immediate change in the flow of execution.
• <break> – Break out of a loop and exit the loop activity.
• <call> – Send a request to a business operation, or to another business process.
• <case> – Perform a set of activities when a condition is matched within a <switch> element.
• <catch> – Catch a fault produced by a <throw> element.
• <catchall> – Catch a fault or system error that does not match any <catch>.
• <code> – Execute lines of custom code.
• <compensate> – Invoke a <compensationhandler> from <catch> or <catchall>.
• <compensationhandlers> and <compensationhandler> – Provide compensation handlers, each of which performs a sequence of activities to undo a previous action.
• <context> – Define general-purpose properties in the business process execution context.
• <continue> – Jump to the next iteration within a loop, without exiting the loop.
• <default> – Perform a set of activities when no matching condition can be found within a <switch> element.
• <delay> – Delay execution of a business process for a specified duration or until a future time.
• <empty> – Perform no action.
• <false> – Perform a set of activities when the condition for an <if> element is false.
• <faulthandlers> – Provide zero or more <catch> and one <catchall> element to catch faults and system errors.
• <flow> – Perform activities in a non-determinate order.
• <foreach> – Define a sequence of activities to be executed iteratively.
• <if> – Evaluate a condition and perform one action if true, another if false.
• <label> – Provide a destination for a conditional branch operation.
• <milestone> – Store a message to acknowledge a step achieved by a business process.
• <parameters> and <parameter> – Specifies the parameters for another BPL element as a set of name-value pairs.
• <process> – Define a business process.
• <property> – Define a property within the <context> element for a business process.
• <pyFromImport> – Specifies optional Python from / import statements.
• <reply> – Send a response from a business process before its execution is complete.
• <request> – Prepare a request within a <call> element.

• <sequence> – Perform activities in sequential order.
• <scope> – Define the error handling mechanisms for a sequence of activities.
• <sql> – Execute an embedded SQL SELECT statement.
• <switch> – Evaluate a set of conditions to determine which of several actions to perform.
• <sync> – Wait for a response from one or more asynchronous requests.
• <throw> – Throw a specific, named fault.
• <trace> – Write a message to the foreground ObjectScript shell.
• <transform> – Transform one object into another using a data transformation.
• <true> – Perform a set of activities when the condition for an <if> element is true.
• <until> – Perform activities repeatedly until a condition is true.
• <while> – Perform activities repeatedly as long as a condition is true.
• <xpath> – Evaluate XPath expressions on a target XML document.
• <xslt> – Execute an embedded XSLT transformation.
