- * section: InputOutput
- * synopsis: Example of custom Input/Output
- * purpose: Demonstrate the use of xmlRegisterInputCallbacks
- * to build a custom I/O layer, this is used in an
- * XInclude method context to show how dynamic document can
- * be built in a clean way.
- * usage: io1
- * test: io1 > io1.tmp ; diff io1.tmp io1.res ; rm -f io1.tmp
