|
| This description is meant to inform the community how to layout
| | http://svn.smallangles.net/trac/canSAS/browser/1dwg/tags/v1.0/doc/cansas-1d-1_0-manual.pdf?format=raw |
| the information within the XML files. However, should the
| |
| information in this document and the [[cansas1d_xsd | canSAS 1D SAS XML Schema]]
| |
| differ, the XML Schema will be deemed to have the most correct description
| |
| of the standard.
| |
| | |
| ==General Layout of the XML Data==
| |
| | |
| ===required XML file header===

| |
| version="0.1a">
| |
| </pre>
| |
| | |
| ;NOTE: We (canSAS) will have to be able to provide the cansas1d.xsd as a page on the WWW. We should use that URL here.
