The options which have to be set for an XML document, which depends on a DTD (document type definition) are in the lower half of the dialog page.
The shown options produce a document, this looks as follows:
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<!DOCTYPE test SYSTEM "data.dtd">
<root>
...
</root>
With the DTD "data.dtd" is checked, whether the document is valid. However, this examination will be done when the document is reloaded in a validating XML processor and is not carried out in the TextTransformer.
If a public DTD shall be used, the corresponding radio button has to be selected and the lower field for the reserve ID is activated. A reserve ID is required.
