Don't use handler.startElement witout specifying a namespace and the
attributes (such as "style") should be specified as last parameter of
the startElement method call.

Same here. Use startElement with namespace and fix attribute.

<xsl:copy-of select="svgDynamique/*"/> should work.

You will need to parse the SVG file and insert it into the FO file via
DOM operations or you use the fo:external-graphic element and specify as
source the SVG file.
