The W3C Technical Architecture Group (TAG) has published The Disposition of Names in an XML Namespace. "This Finding addresses the question of whether or not adding new names to a (published) namespace is a sound practice." Short version: yes, it is. However, "Specifications that define namespaces SHOULD explicitly state their policy with respect to changes in the names defined in that namespace. For namespaces that are not immutable, the specification SHOULD describe how names may be given definitions (or have them removed) and by whom."
Altsoft N.V. has posted a beta of Xml2PDF 3.0, a $49 payware Windows program for converting XSL-FO, SVG, WordML, MathML, and XHTML documents into PDF, SVG, BMP, EMF, TIFF, GIF, JPEG, PNG, or WMF files. 3.0 shoudl be faster and adds support for MathML input and SVG and bitmapped graphic output. "The formatting engine is implemented as pure managed .NET components and can be easily integrated into any .NET-based solution. It does not use any third-party applications or COM components."
