xml catalog造句

Also, the program has support for XML catalogs.
The XML catalog is a document describing a mapping between external entity references and locally cached equivalents.
The validating DTD may be identified by using XML Catalogs to retrieve its specified " external subset ".
An XML catalog is an XML file of a specific format that maps a schema definition string to an actual file name on the disk or web.
In addition, documents for these XML schema languages must be parsed separately, so validating the schema of XML documents in pure standalone mode is not really possible with these languages : the document type declaration remains necessary for at least identifying ( with a XML Catalog ) the schema used in the parsed XML document and that is validated in another language.
