Whitespace rules are not defined in XML

[jmccrae]

Whitespace rules in the XML are not clearly defined. For example consider this

                <exampleTranslation>
                    <text>
                            Koroner <collocateMarker lemma="provést">provedl</collocateMarker>
                            <headwordMarker>pitvu</headwordMarker>.
                    </text>
                </exampleTranslation>

How do we know that the whitespace is a single character between 'provedl' and 'pitvu', while the whitespace before 'Koronoer' and after '.' is not part of the translation?

Blocking implementation of #61

Related is is the use of labels in collocateMarkers for which there is no example, but the whitespace rules around labels should be considered too

<collocateMarker>
   This is a collocate marker
   <label tag="foo"/>  <!-- is the whitespace part of the collocate marker? -->
</collocateMarker>

Decision Dec 12 meeting:
Explain whitespace handling in XML serialization intro
Introduce whitespace attribute on the affected elements (consider defaults)
Review xml whitespace implementation in next meeting

• I have added a paragraph to the “design principles” section (at the start of the XML serialization section) which states that whitespace should always be collapsed (which includes removing leading and trailing whitespace) unless otherwise stated.
• On each XML element that can take inline markup, I have “otherwise stated” that whitespace inside it should be preserved.
• I have updated the examples (in the “Examples” section) to not contradict that.
