The second limitation comes from the fact that the current styling tools for rendering an XML document, such as CSS (Cascading Style Sheets), which are a strictly layout-oriented language, or XSLT (XSL transformation language), which is a more generic tool for transforming an XML document into another one (such as a displayoriented HTML file) are poorly adapted to linguistic processing.
it seems difficult in such formalisms to express such basic grammatical facts as number or gender agreement.
