node-set fit-document(string uri)
The fit-document function accepts exactly one argument that is converted to a string. The argument must be an URI pointing to a fit://-URL, otherwise an empty result is returned and an error will be raised. The resource referenced by that URL is retrieved and the data resulting from the retrieval action is parsed as an XML document and a tree is constructed in accordance with the data model.
If the content pointed to by the URI can be retrieved and parsed, the fit-document function returns a node-set containing the document node at the root of the resulting tree. When attempting to access non-existent content, the node-set will be empty.
The fit-document function is similar to the XSLT document() function.
