> [G. Ken Holman's explanation] hmmm.... so doc() and docref() do essentially the same thing, except that doc takes a scalar argument, and docref takes a vector (node-set) argument? are there any dictums about what sort of URI a compliant processor must know how to handle? for example, at least "http:" and "file:"? how about a pipe? how does the processor signal that: - it doesn't know how to handle the uri's scheme - it gets an access denied error accessing the resource - the resource does not exist - the resource is not well-formed - the resource has nothing in it what dtd is the resource validated against? suppose i have a source xml document with an xlink: <employee> <employer xml:link="simple" href="http://some.company.com/employer.xml" show="embed" actuate="auto"> </employee> and stylesheet fragment like this: <xsl:apply-templates select="employee/*"/> would a compliant XSLT processor have to deal with the above the same as if it were given this source: <employee employer="http://some.company.com/employer.xml"/> and had this stylesheet fragment: <xsl:apply-templates select="doc(@employer)"/> ? does the processor timeout if it can't get the resource in time? is that a system-property? is a compliant processor prohibited from loading resources from doc/ref expressions that aren't activated, and must any other resource exactly once? can it load the ones it will load in parallel and in any order? if i understand this correctly, for the sanity of xslt programmers it is actually now necessary for XPointer and XSLT to converge, since doc/ref would naturally use xpointer syntax in uri, while the rest of a style sheet uses xslt expressions? -mda XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
