Hi,

I'm currently working on a data export program which will create an XML
Excel file using SpreadsheetML.

I have downloaded all the relevant documentation for Excel 2003 XML files
but can't find any information about which namespace each attribute belongs
to.

For example, Excel defines the following namespaces in the workbook
element:

<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet"
 xmlns:o="urn:schemas-microsoft-com:office:office"
 xmlns:x="urn:schemas-microsoft-com:office:excel"
 xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet"
 xmlns:html="http://www.w3.org/TR/REC-html40"> 

Later on, the table element attributes are using these namespaces:

<Table ss:ExpandedColumnCount="10" ss:ExpandedRowCount="1"
x:FullColumns="1" x:FullRows="1" ss:DefaultColumnWidth="60">

All of the attributes belong to the "ss" namespace, only FullColumns and
FullRows belong to "x" - but I can't find a reference with all possible
attribute and namespaces.

The table element alone has around 20 attributes - not sure how I can
create a valid XML without the correct namespaces.

Any ideas / hints?

thanks & regards
thomas
