Differentiate between validating and non validating parser dating in ghaziabad
Therefore, the term "Default Namespaces" is inherently incorrect.Declaring a means that any element within the scope of the declaration will be qualified implicitly, if it is not already qualified explicitly using a prefix.There was no reason why this should not have been allowed in 1.0, but the mistake has been rectified in 1.1.It is necessary to know this difference because not many XML parsers yet support Namespaces in XML 1.1.
Thus, we see that the namespaces in XML concept is not very different from packages in Java.
Just as shelves partition the entire space in a refrigerator, the symbol spaces partition the namespace.
There are three primary partitions in a namespace: one for global element declarations, one for global attribute declarations, and one for global type declarations (complex Type/simple Type).
Note that the prefixes are used only as a placeholder and must be expanded by the namespace-aware XML parser to use the actual namespace bound to the prefix.
In Java analogy, a namespace binding can be correlated to declaring a variable, and wherever the variable is referenced, it is replaced by the value it was assigned.
