XML 的一些总结
XML Namespace
xml:lang and xml:space
As of the last update of this document, the XML 1.0 Specification (Fifth edition) (and also the XML 1.1 Specification Second edition) defines two attribute names in this namespace:
xml:lang- Designed for identifying the human language used in the scope of the element to which it's attached.
xml:space- Designed to express whether or not the document's creator wishes white space to be considered as significant in the scope of the element to which it's attached.
xml:base
The XML Base specification (Second edition) describes a facility, similar to that of HTML BASE, for defining base URIs for parts of XML documents. It defines a single attribute, xml:base, and describes in detail the procedure for its use in processing relative URI refeferences.
xml:id
The xml:id specification defines a single attribute, xml:id, known to be of type ID independently of any DTD or schema.
