Using the pretty print option results in invalid XML if processing instructions are \
                embedded in enumerated elements
-------------------------------------------------------------------------------------------------------------------


                 Key: XMLBEANS-384
                 URL: https://issues.apache.org/jira/browse/XMLBEANS-384
             Project: XMLBeans
          Issue Type: Bug
    Affects Versions: Version 2.4 
            Reporter: Scott Roeske
            Priority: Minor


If an element contains a processing instruction, it is separated into multiple lines \
when using the pretty print option. 

For example:   
    <elem><?proc_instr?>text</elem>

Becomes:
    <elem>
      <?proc_instr?>
      text
    </elem>

This causes problems if the element is an enumerated type since the extra whitespace \
results in invalid XML.  If the output is subsequently parsed, then the following \
exception is raised when trying to validate the document or trying to access the \
value:

    org.apache.xmlbeans.impl.values.XmlValueOutOfRangeException: string value '
        
        text
    ' is not a valid enumeration value for type of elem element in type of element \
doc

In this case, the newlines that have been introduced have resulted in a value that \
does not match any of the valid enumerated types.  

The workaround is to use the "strip whitespace" option when parsing the output, which \
collapses the value back to a single line and results in valid XML again.  However, \
this workaround may not always be possible or desirable, and it would be preferable \
if the pretty print output could result in valid XML from the outset.
