The XXE (XMLmind XML Editor) is designed not to break XML documents. If a well-formed XML document is loaded, it is not possible to create ill-formed XML. In addition to that, a schema is loaded that checks if the structure and values of the XML are coherent (or valid in XML terms). The schema also controls which tags can be inserted at a specific position in a document. This is a great help while editing XML files for EOA.
For example, a bibliographical reference is created by a
ref element inside a
bibl element. The
ref element requires as attributes
* the cited work in form of a short citekey (e.g.
Needham:1954, prefixed with
* the way the citation should be rendered (as author and year or simply the year)
All this information is stored in the schema, and by inserting a new
bibl element, a boilerplate of this structure is inserted:
Moreover, the since in the context of a bibliographical reference the
type attribute of
ref can be nothing else but
year, only these two values are offered when specifing the value:
