Missing something basic . . ?

Hello,

 

I am trying to process some zipped text files in xproc (leveraging a
Calabash extension), but I am getting tripped up by base64 encoding.

 

My first draft of the xproc is below. Unfortunately, the content-type option
on cx:unzip seems to be getting ignored and I end up with an output file of
the following nature:

 

<!-- Output Snippet -->

<c:data xmlns:c="http://www.w3.org/ns/xproc-step" name="InputFile1.txt"
content-type="">LS0tLS1CRUdJTiBQUklWQUNZLUVOSEFOQ0VEIE1FU1NBR0UtLS0tLQ0KUHJv
Yy1UeXBlOiAyMDAx . . . </c:data>

 

I am I missing the obvious . . . or trying to do the impossible?

 

Most grateful for any feedback,

 

Christopher
