Here's some thoughts. You can use any XML table syntax which has rows containing cells and use XLL. If you have given all the rows IDs, then you can use something like www.you.com/code-table.xml#ID(row1) Check the XLL draft. Check the Xptr draft for how to use it in an element. Your email was truncated again, but if you wanted an element for each row, you could go something like this (ruching this off-attribute names probably wrong--better than nothing) <!ELEMENT row1 EMPTY> <!ATTLIST row1 href CDATA #FIXED "http://www.you.com/code-table.xml#ID(row1)" behaviour CDATA #FIXED "embed" action CDATA #FIXED "auto" ...> You then just use <row1/> <row2/> and so on. You need to have an XLL linker available. The same thing can be achieved having in the DTD: <!ENTITY row1 "http://www.you.com/code-table.xml#ID(row1)" > and then putting in the instance: &row1; of course. But again, your parser has to understand XLL. You can use HTML tables and WIDL to specify a row. I think it looks like table[1].row[1] to select the first row from the first table. You would need to specify WIDL notation was being used and have a WIDL processor available. The king of location and embedding syntaxes is called HyTime. It lets you specify an incredible range of things, and brings in a lot of convention to allow you to use external query syntaxes. It is influencing XLL a lot, but XLL is definitely more targetted for smaller WWW applications. Your external table does not need to be in XML. A table of comma seperated pairs could be specified using a notation: <!NOTATION cs-pair PUBLIC "+//IDN ABSYSINFO.COM//NOTATION Comma Separated Pair//EN" "text/x-csp"> <!ENTITY code-table "http://www.you.com/code-table.txt#ID(row1)" NDATA csv> Again, note that that case, you have to have a special parser which reads the comma sepearted pairs into an DOM, labels the columns and rows, and attaches appropriate positional attributes. This could presumably be done by merely having a little utility to convert it to XML at the client! But why not just use XML in the first place? Rick Jelliffe xml-dev: A list for W3C XML Developers.
