# Changes to Serialization

The `saxon:byte-order-mark` attribute on `xsl:output` and `xsl:result-document` is replaced by `byte-order-mark`: that is, this is no longer a Saxon extension but is now a standard feature. At present, the default is "no", regardless of the encoding.

The Windows-1252 codepage is now fully supported as an output encoding. The class to achieve this is taken from the Docbook distribution; it was originally written by Pontus Haglund.
