Text Generation of XML

It works for XML Since XML is really just a text-based format, you can generate XML documents using the same tools you use to generate other forms of text.
Bugs are brutal Logic bugs which sometimes but don't always produce badly-formed XML can be extraordinarily difficult to root out.
Inflexible While you can sometimes reuse text-generation code, it's often difficult to repurpose it to handle new data structures.
Managing text-gen templates as XML is difficult A lot of text-generation systems use syntax which is illegal in XML, making it impossible to apply XML-based tools to the templates themselves.
