Applying Optimization Techniques

• XML offers much finer granularity of application (per-element) than traditional HTTP optimization (per-message).

• To associate a technique with an element, different mechanisms might be used:

  • External XML
    • Markup in XML Schema
    • Markup in WSDL
    • Message Header (using Xpath, etc.)
  • Inline XML
    • Attributes <foo m:cache=&#-109;30&#-108;>
    • Namespaces <m:cache value=&#-109;30&#-108;><foo/></m:cache>
