In the XML Schema world these are known as list data types. Requirement 4.4 of XPath 2.0 reads: 4.4 Should Add List Data Type to the Type System of the Expression Language XML Schema allows the definition of simple types derived by list, including lists of unions of non-list simple types. XPath 2.0 SHOULD support an ordered list of simple-typed values. So you can probably expect support for handling these kinds of things with a function come XPath 2.0/XSLT 2.0. In the short term, there is one function that may help, namely the id() function, which can take a space-separated string and locate the elements with those IDs in a document. However you have to jump through some hoops to use it in any useful way, and it's often easier to use an extension function (e.g. exsl:tokenize(), saxon:tokenize(), xalan:tokenize()) or write a recursive template that either acts on each of the values as it finds them or returns a result tree fragment that you convert to a node set using a node-set extension function (you can use the one at http://www.exslt.org/str/functions/tokenize/str.tokenize.template.xsl if you like).
