The xsl:number element works by walking up the document tree and counting the specified elements. A nodeset created with dovcument() is not attached to the main document, and xsl:number can't walk up the tree. You end up with incorrect numbers.
A solution to this problem is to pipeline two transformations: the first one aggregates all sub-documents into one, and the second transformation applies the styles and numbering.
Another solution could, using only one transformation, build a unique nodeset (using xalan:nodeset for example) containing all sub-documents, and then apply the numbering on that nodeset.
I included a example of the first solution, implemented as an OXF pipeline. Please let me know if you have further questions.

Sorry for missing XSL ... here's the code...
explain: When using the attribute 'file' I'm loading the given xml document and applying the content, otherwise I'm using the numbering (section-title). In addition there's creating an anchor for that section, and calculating the depth for assign a stylesheet 'title' numbered from '0' to 'n'. At lease the content gets applied. That's it.
