FGDC metadata validation causing StackOverflowError

[mattblanchette]

Attempting to validate FGDC metadata with long enough strings of text (for example 1400 characters in the Abstract) causes a StackOverflowError from the FGDCstring regular expression "\s*\S(.|\n|\r)*" in the schema.

Replacing this regular expression restriction in the FGDC schema.xsd with whitespace collapsed and a minlength of 1 will prevent the Error.

Before:
<xsd:pattern value="\s*\S(.|\n|\r)*"/>

After:
<xsd:whiteSpace value="collapse"/>
<xsd:minLength value="1"/>
