Indicates that the file should be parsed as XML.
<?XML version="version" standalone="DTDflag" encoding="encname" ?>
This declaration must be the first element (including white space) in the file.
The existence of this declaration puts the script component compiler into strict XML mode where element types and attribute names are case-sensitive, attribute values must be in single or double quotes, and all elements are parsed. If the declaration is not included, the compiler allows looser syntax.
In general, you should include this declaration and follow XML conventions if your script component file will ever be edited in an XML-conformant editor.
<?XML version="1.0" standalone="yes" encoding="UTF-16" ?>
