In contemporary settings, XML stands as a prevalent standard for multimedia and cross-platform technical document publishing. A multitude of editing applications, management systems, and publication tools, along with various industry standards, rely heavily on XML. Despite its widespread adoption, XML has struggled to gain traction in certain domains due to its distinct separation between document structure and layout. Editors often lean towards using word processors like Microsoft Word, where text and formatting are developed concurrently, allowing for immediate visual feedback. Conversely, XML demands a more abstract mindset, as the content is interspersed with structural tags, with the layout being established only in later production phases. In contrast, SimQin enhances the user experience by presenting documents in layout mode from the beginning while also revealing the underlying XML structure and organization. This dual visibility can streamline the editing process and potentially increase XML's appeal among users accustomed to traditional word processing tools.
