Inconsistent quotations in serialized XML declaration

[david-waltermire]

Describe the bug

Serialized output XML declaration includes inconsistent quotations. i.e "value" vs 'value'

Who is the bug affecting?

Users that serialize into XML.

What is affected by this bug?

The serialized XML output is valid but uses inconsistent quotation within the file and is not consistent with the input file.

When does this occur?

When serializing a OSCAL document node into XML.

How do we replicate the issue?

1. Modify OscalBindingContextTest.testLoadCatalogXml(@TempDir Path tempDir) to no longer delete the output.
2. Execute test.
3. Review test output file.

Output

<?xml version='1.0' encoding='UTF-8'?>
<catalog xmlns="http://csrc.nist.gov/ns/oscal/1.0" uuid="4cd70b73-a0be-4bf5-9cc6-6535dd251939">
  <metadata>
...

Expected behavior (i.e. solution)

<?xml version="1.0" encoding="UTF-8"?>
<catalog xmlns="http://csrc.nist.gov/ns/oscal/1.0" uuid="4cd70b73-a0be-4bf5-9cc6-6535dd251939">
