Discussion of using the “lax” function in Schema Documents

We’ve recently changed how we are structuring our XSD schemas by adding a “lax” process function element at the end of the sequence.  The ‘lax’ function, or ‘any Element’ function, can be specified by the author of the schema document, and enables additional elements not specified by the schema to be included.

Validation of XML data interchange documents with normative schemas using free, open-source software (XML Explorer)

One of the objectives of the US Geoscience Information Network (USGIN) is to establish a community of practice for developing, documenting, adopting, and using standard document encoding for data interchange. The technology for encoding schemes is evolving continuously, and current practice is to use XML encoding with data schema defined by XML schema.
