XSLT function: node-set document (object, node-set?)

Standard excerpt:

The document function allows access to XML documents other than the main source document. When the document function has exactly one argument and the argument is a node-set, then the result is the union, for each node in the argument node-set, of the result of calling the document function with the first argument being the string-value of the node, and the second argument being a node-set with the node as its only member. When the document function has two arguments and the first argument is a node-set, then the result is the union, for each node in the argument node-set, of the result of calling the document function with the first argument being the string-value of the node, and with the second argument being the second argument passed to the document function. When the first argument to the document function is not a node-set, the first argument is converted to a string as if by a call to the string function. This string is treated as a URI reference; the resource identified by the URI is retrieved. The data resulting from the retrieval action is parsed as an XML document and a tree is constructed in accordance with the data model (see [3 Data Model]). If there is an error retrieving the resource, then the XSLT processor may signal an error; if it does not signal an error, it must recover by returning an empty node-set. One possible kind of retrieval error is that the XSLT processor does not support the URI scheme used by the URI. An XSLT processor is not required to support any particular URI schemes. The documentation for an XSLT processor should specify which URI schemes the XSLT processor supports.
Examples (xslt:xml):

Interactive xlab: [xsl:value-of] [xsl:template]
