Example
Take as an example the following text data stream which gives the name, age and location of a person:
The logical model for this data can be described by the following fragment of an XML Schema document. The order, names, types and cardinality of the fields are expressed by the XML schema model.
To additionally model the physical representation of the data stream, DFDL augments the XML schema fragment with annotations on the xs:element and xs:sequence objects, as follows:
The property attributes on these DFDL annotations express that the data are represented in an ASCII text format with fields being of variable length and delimited by commas.
An alternative, more compact syntax is also provided, where DFDL properties are carried as non-native attributes on the XML Schema objects themselves.

Famous quotes containing the word example:
“Our intellect is not the most subtle, the most powerful, the most appropriate, instrument for revealing the truth. It is life that, little by little, example by example, permits us to see that what is most important to our heart, or to our mind, is learned not by reasoning but through other agencies. Then it is that the intellect, observing their superiority, abdicates its control to them upon reasoned grounds and agrees to become their collaborator and lackey.”
—Marcel Proust (1871–1922)
