When you edit the XML target in the Target Designer, you can also specify a DTD or schema file name for the target XML file. The Integration Service adds a document type declaration or schema reference to the target XML file and inserts the name of the file you specify. For example, if you have a target XML file with the root element
and you set the DTD Reference option to
, the Integration Service adds the following document type declaration after the XML declaration:
<!DOCTYPE TargetRoot SYSTEM "TargetDoc.dtd">
The Integration Service does not check that the file you specify exists or that the file is valid. The Integration Service does not validate the target XML file against the DTD or schema file you specify.
An XML instance document must refer to the full relative path of a schema if a midstream XML transformation is processing the file. Otherwise, the full path is not required.
