XSD Schema Update: Changed the position attribute of the LSItem element from required to optional in ilias_lso_9_0.xsd. This ensures that XML files from older versions pass the schema validation.
• Robust XML Parsing: Updated ilLearningSequenceXMLParser to check for the existence of the position attribute before attempting to store it in the internal data array.
• Safe Importing: Modified ilLearningSequenceImporter to only apply the item order number if the position data is actually available in the imported set. If missing, the default sorting of the system is used.
