public class SimpleContentFeed extends AbsorptionFeed
The result of this Watch is a single string, constructed using the rules of "Constructing Simple Content" in the XSLT specification.
The AdjacentTextNodeMergerFeed is used when the node is constructed as a result of a computation on the streamed data,
for example xsl:value-of select="distinct-values(.//@price)". By contrast, a SimpleContentWatch
is used when the streamed nodes are selected directly, for example xsl:value-of select=".//@price".
Both a Feed and a Watch are needed because a simple content constructor operates on a sequence of nodes without simply atomizing the sequence.

makePendingItem(int sequenceNr,
FleetingParentNode node)
Create a pending item (appropriate to the subclass) containing the data needed
to compute the result value for one node in the streamed input sequence

protected Sequence<?> |
processGroundedItem(Item item)
Process a grounded item in the input sequence: either a streamed leaf node such as an attribute
or text node, or an atomic value, or a non-streamed element or document node injected into the
sequence for example by use of the comma operator.
