I just try things with XSLT. My documents are usually TEI-friendly, but mistakes are possible. Feel free to adapt them. My xsl files are often not perfect and need modifications to fully work. Do not hesitate to suggest tricks if you have some !
You can use oXygen or the xslt processor you want. Be careful to use a processor that support xslt functions used in the xsl file. (for example PHP's XSLT processor only handles XSLT1.0)
My xsl generally use XSLT3.0 ; otherwise restrictions will be shown in the readme.
Have fun !
