com.volantis.xml.expression.sequence.Sequence
A sequence of items.
Warning: This is a facade provided for use by user code, not for implementation in user code. User implementations of this interface are highly likely to be incompatible with future releases of the product at both binary and source levels.

Indices for sequence items are in the range from 1 to the length of the sequence inclusive. Sequence indices are NOT zero based like Java arrays.
