Attribute values containing special chars shouldn't be touched.

Description

When formatting XML where an attribute has a value that contains special chars (like single quotes) they also become formatted:

Input:

<!DOCTYPE xml>
<core:FragmentDefinition xmlns="sap.m" 
    xmlns:core="sap.ui.core">
        <Text text="{parts: ['i18n>dialog.countdown.text','view>/Countdown'],formatter: 'jQuery.sap.formatMessage'}" />
    </Dialog>
</core:FragmentDefinition>

Format once:

<!DOCTYPE xml>
<core:FragmentDefinition xmlns="sap.m" 
    xmlns:core="sap.ui.core">

    <Text text="{parts: ['
        i18n>dialog.countdown.text','
        view>/Countdown'],formatter: '
        jQuery.sap.formatMessage'}" />

</core:FragmentDefinition>

Format twice:

<!DOCTYPE xml>
<core:FragmentDefinition xmlns="sap.m" 
    xmlns:core="sap.ui.core">

    <Text text="{parts: ['
    
        i18n>dialog.countdown.text','
    
        view>/Countdown'],formatter: '
    
        jQuery.sap.formatMessage'}" />

</core:FragmentDefinition>

The more you format it, the more newlines will be added in the text attribute. Imo the input shouldn't be formatted further, as it's already intended correctly and every attribute is on its own line.

This was fixed in issue #187, but I've added this sample XML as a test case to ensure things like braces don't end up breaking in the future as I don't personally run into it very often.
