General XML Rules

All xml batch input files must be well formed and valid.

To be well formed:

      The file must begin with the XML declaration.

      The document must have a root element.

      All elements (tags) must have a closing tag.

      Tags are case-sensitive.

      The elements must be properly nested.

      Attribute values must be quoted.

To be valid, an XML document must conform to the rules of a DTD or schema that defines the structure of the document (for example, the order of tags, the number of tags allowed of a certain type, the type of tag content accepted, etc.).
