Non validating parser xml
The reason is that XML software should be small, fast, and compatible.HTML browsers are allowed to display HTML documents with errors (like missing end tags). A "well formed" XML document is not the same as a "valid" XML document. In addition, it must conform to a document type definition.If the XSD is publicly available using HTTP and referenced through a "schema Location" or "no Namespace Schema Location", then the validator will pick it up and it doesn't need to be specified/uploaded.*The maximum size limit for file upload is 2 megabytes.
XSD files are "XML Schemas" that describe the structure of a XML document.However, this makes no difference when using the Expat parser.Expat is a non-validating parser, and ignores any DTDs.However such a format would have no convenient commands for typesetting, and so normally xmltex will be used on top of an existing format, normally La Te X.In this section we assume that the document to be processed is called .
