According the MS press release, Office 10 has two features that seem like they would have been perfect with DeepLeap:

• **Native XML support.**Excel and Access now support XML as a file format and can easily import and export XML data. This enables organizations to build solutions that integrate Excel or Access as the front end to XML-based data structures to improve corporate reporting and analysis.
• **Extensible Smart Tag architecture.**Smart Tags are built on an extensible architecture so that developers can create new Smart Tags to help Office users gather information from the Web, such as accessing real-time sales or inventory data while working in Excel.
