Lustre's XML-based files have the following limitations:

• Certain functions have not been implemented.
• You can only include hard returns in the structure tags. You must include all other tags and their contents (opening tag, value, and closing tag) in a single line.
• You can use XML features that are included in the predefined tag list only. This is to ensure optimized performance.
• The Lustre XML parser ignores tags that you use to store additional information.
