signnamespaces

Specifies which namespaces are filtered for a particular signature.

Filtering a namespace means keeping or omitting all of the form elements and attributes that are in the specified namespace.

For example, if a signnamespaces option specifies that the http://www.ibm.com/xmlns/prod/XFDL/Custom namespace should be kept, then all elements in that namespace are signed.

Syntax

   <signnamespaces>
      <filter>namespace filter</filter>
      <uri>namespace URI₁</uri>
      ...
      <uri>namespace URI_n</uri>
   </signnamespaces>

Note: There may be any number of namespace URI entries.
