Some characters have a special meaning in XML.
If a “less than”( "<" ) character is placed inside an XML element, it will generate an error because the metadata parser interprets it as the start of a new element.
It will generate an XML error:
<abstract> if salary < 1000 then </abstract>.
To avoid this error, replace the "<" character with an entity reference:
<abstract> if salary < 1000 then </abstract>
There are 5 predefined symbols that need to be converted to codes:
Less than: < use <
More than: > use >
Ampersand: & use &
Apostrophe: ' use '
Quotation: " use "
