Reference URI format !

[Ling Xiaohan]

Hi,

   URI attribute of <Reference> tag can be set to a relative path in local 
file
system, but when the path contains blank space, it seems this <Reference>
tag coulde not be created by XMLSignatureFactory.newReference method.
Ex.,
   <Reference URI="My document/test.txt">
where there is a space in "My document".

Is this a limit?

Thanks.
