Response to: Wondering whether brackets are needed to have a sequence
To identify a sequence, I was following the model at http://www.w3.org/TR/xpath20/#id-sequence-expressions, which shows that parentheses are required. I never tried it without them. Bob

  But the section you refer to is about constructing sequences from atomar values, there you need () to construct a sequence. Your example however uses an XPath expression with an element name as a node test and in XPath 1.0 that results in a node set why it is my understanding that in XPath 2.0 it results in a sequence of nodes.
  Indeed if I try the example with Saxon 7.5 without the () around color then the result is the same as with (color).
