xs:string - Isn't whitespaces preserved by default?

[dave <ceek63@yahoo.com>]

I have an xs:string type element to hold some regex
expressions. I haven't put any restrictions/facets for
this xs:string type. Isn't by default, it should
preserve whitespace? Looks like the leading and
trailing spaces are removed when I generate an XML
using XmlBeans apis.

In general, what is the better XSD data type to hold
regex patterns? Is it just xs:string OR should I
explicitly preserve Whitespace for this xs:string?
