Forrest also uses the XML Document Type Declaration to effect the Content Aware Pipelines.
Remember that you are not required to use DTDs (for example Forrest can also respond to a namespace) so RELAX NG or W3c XML Schema can be used.
This validates all of the important configuration files, both in Forrest itself and in your project.
At the moment it processes all files, all files, and all XSLT stylesheets.
Our download format adds a group of new elements to the standard 'documentv13' format.
Our new elements are described by the following DTD: element is to be allowed wherever "local sections" are used.
When a source document uses a DTD to define its structure, then various abilities are enabled.
Forrest handles the annoying side of this and takes advantage of the benefits.
Forrest uses the XML Catalog syntax by default, although the older plain-text format can also be used.We cannot rely on the subsequent "system identifier" part ("download-v10.dtd"), because as a relative reference it is liable to break.The solution Forrest uses is to ignore the system id, and rely on a mapping from the public ID to a stable DTD location, via a Catalog file.XML stands for extensible markup language, which uses tags to surround and denote data points within a hierarchical architecture.One of the powerful advantages of XML is high flexibility; XML specifies the organization of data very well but does not define or restrict the types of information it can contain.
