  XML and XML Schema are widely used in different domains for the definition of
standards that enhance the interoperability between parts exchanging
information through the Internet. The size and complexity of some standards,
and their associated schemas, have been growing with time as new use case
scenarios and data models are added to them. The common approach to deal with
the complexity of producing XML processing code based on these schemas is the
use of XML data binding generators. Unfortunately, these tools do not always
produce code that ?ts the limitations of resource-constrained devices, such as
mobile phones, in the presence of large schemas. In this paper we present
Instance-based XML data binding, an approach to produce compact
application-specific XML processing code for mobile devices. The approach
utilises information extracted from a set of XML documents about how the
application make use of the schemas.
