## Example

- The example shows entity references using data from XS-S-1.
- The VSP page has a button for retrieving title elements from a selected document, where the title element contains a substring.
- The example uses the 'xpath-contains' predicate.
- The VSP page has a second button with the same function using text-contains.
- This illustrates that xcontains + text-contains does not go through links, but that xpath_contains + contains does.
- The example has a viewer for the source of each page so that the entity references can be seen.
- The page has some of the rows of the text table as persistent XML and others as text.
- The columns are declared as ANY in SQL. This illustrates the late binding dependent on representation.
