The Structure pane lets you view, edit, and manage XML elements. You use the Structure pane in many ways when
working with XML. For example, to place imported XML content into the layout, you can drag elements from the
Structure pane directly to a page. You also use the Structure pane to adjust the hierarchy of the elements. You can add
elements, attributes, comments, and processing instructions by way of the Structure pane.
The Tags panel lists tags for elements. You can import, export, add, delete, and rename tags. You use the Tags panel to
apply element tags to content that you plan to export to XML, and to apply tags to frames before importing XML
content into them.

About DTD files
To share XML data with others, you need to agree on a standard set of tag names and element attributes so that everyone
in your group uses and applies tags the same way. One method for handling the sharing of XML data is to use a
document type definition (DTD) file.
A DTD file provides a set of elements and attributes for members of the group to use. It also defines the rules about
where elements can appear in the structural hierarchy. For example, the DTD file may require the Title element to be a
child of the Story element because the title is supposed to appear inside the story; if you tag a title without tagging the
story it appears in, the DTD file marks the Title element as invalid. You can search for and flag invalid structural errors
in an InDesign file with a DTD file. This process is called validating.
