The attribute type is not visible in the XPath tree model and has no effect
on the way a stylesheet is processed (unless the type is ID, which affects
the id() function).

Splitting up an ENTITIES value is therefore the same as processing any other
space-separated string, it can be done using a recursive named template
using the substring-before() and substring-after() functions, or using the
tokenize() extension function present in Saxon and Xalan.
