Hi John; We choose to define our own id and idRef elements because the semantics of the native XML definitions only allowed the scope to be within a single XML document. Since many of the topology elements are long lived, we need semantics that could allow references between documents. Hope this helps; -jason On 2/23/11 2:45 AM, John MacAuley wrote:
Peoples,
I started to capture the different example XML instance documents into a reference XML schema but have a number of questions. The first question is the use of id and idRef attributes that appear in the examples. I had assumed these were standard XML attributes, however, the URN values in the example XML are not compatible with the XML ID and IDREF attribute types (":" are not allowed in NCNames). Can I use the XML base anyURI type for this?
Thank you, John.
