I have written a package for converting XMLs to ePubs. Everything works fine, except some cases, where blank namespace (xmlns="") nodes are being written to the result-documents. Prior to transformation, I prepared temporary variables for holding main-segments(i.e., meta, body etc.) and finally copied the nodes(using xsl:copy-of[@copy-namespaces='no'] instruction) to result-document. I also have used @exclude-result-prefixes='ns_list_sep_by_space' within xsl:transform element and still not able to get desired result.
oXygen IDE shows a message in pop-up saying:
When using xsl:copy-of the new elements will also have namespace nodes copied from the original element node, unless they are excluded by specifying copy-namespaces="no". If this attribute is omitted, or takes the value yes, then all the namespace nodes of the original element are copied to the new element. If it takes the value no, then none of the namespace nodes are copied: however, namespace nodes will still be created in the result tree as required by the namespace fixup process.
Here is some more details of my problem:

<!--

2/ declaration «xmlns:cylian='local-ns-for-extension-functions'» has to retain, some parts of transformation uses some extension functions from that namespace
-->
</xsl:transform>
and here's the output:
a.html

I hope it would be easier to understand what's the problem is going on. All suggestions are welcome. Thanks in advance.
