You can find relevant information to the MSDN website. XML support has been added to Word 2003. Word has been fully designed for XML. It supports native XML vocabulary called Word Mark Language (Wordml). Readers can see more information about Wordml from Microsoft Office Word 2003 Preview. One of this worth noting is that Word 2003 also supports XML to other transformations. When saving a document, Word 2003 can apply XSLT conversion during the save process. You can specify a conversion by selecting the "Apply Transform" option in the "Save AS" dialog. Simply select a XSLT from the disk, Word will run the conversion and output the result when you save this document. Microsoft also provides the build tool WordProcessingml Transform Inference Tool for the XSL Conversion Architecture required to convert from XML to other formats.
