XML context item is handled as a string
When you assign a childless XML to a context item, BMC Atrium Orchestrator assumes that the context item value is contained in the text content only.
However, if there are children, then the value is the entire XML document: <list><element color="blue">sample</element></list>.
Workaround
Use the embedded XML. If a childless node is required for processing, create the node using XSLT.
