问题
Need help with building an XSL version 2.0 file in converting XML file to text output.
Below is the XML file. For all the elements that have field as "Checked = 'Y'" we need a "[X]" concatenated before the text output.
Tab spaces should be based on the level of ansestor-tags.

In your XSLT, you seem to be only selecting elements where Checked is "Y"
<xsl:for-each select="descendant-or-self::*[@Checked='Y']">
So, all other elements are ignored. I think you should be selecting elements with a Txt attribute here:
<xsl:for-each select="descendant-or-self::*[@Txt]">
(And similarly for the count)
Then, to determine whether to show an "[X]" at the front, you can do this:
<xsl:if test="@Checked='Y'">[X] </xsl:if>
<xsl:value-of select="@Txt"/>
Or maybe this:
<xsl:value-of select="concat(if (@Checked = 'Y') then '[X] ' else '', @Txt)"/>
Try this XSLT
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
exclude-result-prefixes="xs"
version="2.0">
<xsl:output indent="yes" method="text"/>
<xsl:strip-space elements="*" />
<xsl:template match="ReviewSummaryXML">
<xsl:for-each select="descendant-or-self::*[@Txt]">
<xsl:call-template name="tab">
<xsl:with-param name="ancestor-count" select="count(ancestor::*[@Txt])"/>
</xsl:call-template>
<xsl:value-of select="concat(if (@Checked = 'Y') then '[X] ' else '', @Txt)"/><xsl:text>
</xsl:text>
</xsl:for-each>
</xsl:template>
<xsl:template name="tab">
<xsl:param name="ancestor-count"/>
<xsl:for-each select="1 to $ancestor-count">
<xsl:text>	</xsl:text>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
Note the use of xsl:strip-space too, to avoid excess whitespace being output before your text.
EDIT - In answer to your comment, if you only want to output elements where @Checked is "Y" or they have a descendant that has @Checked equal to "Y", add the condition [descendant-or-self::*/@Checked='Y'] to the relevant expressions.
Try this XSLT:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
exclude-result-prefixes="xs"
version="2.0">
<xsl:output indent="yes" method="text"/>
<xsl:strip-space elements="*" />
<xsl:template match="ReviewSummaryXML">
<xsl:for-each select="descendant-or-self::*[@Txt][descendant-or-self::*/@Checked='Y']">
<xsl:call-template name="tab">
<xsl:with-param name="ancestor-count" select="count(ancestor::*[@Txt][descendant-or-self::*/@Checked='Y'])"/>
</xsl:call-template>
<xsl:value-of select="concat(if (@Checked = 'Y') then '[X] ' else '', @Txt)"/><xsl:text>
</xsl:text>
</xsl:for-each>
</xsl:template>
<xsl:template name="tab">
<xsl:param name="ancestor-count"/>
<xsl:for-each select="1 to $ancestor-count">
<xsl:text>	</xsl:text>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
EDIT 2: If you want an XSLT 1.0 solution, try this....
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
exclude-result-prefixes="xs"
version="1.0">
<xsl:output indent="yes" method="text"/>
<xsl:strip-space elements="*" />
<xsl:template match="ReviewSummaryXML">
<xsl:for-each select="descendant-or-self::*[@Txt][descendant-or-self::*/@Checked='Y']">
<xsl:call-template name="tab">
<xsl:with-param name="ancestors" select="ancestor::*[@Txt][descendant-or-self::*/@Checked='Y']"/>
</xsl:call-template>
<xsl:if test="@Checked = 'Y'">[X] </xsl:if>
<xsl:value-of select="@Txt"/>
<xsl:text>
</xsl:text>
</xsl:for-each>
</xsl:template>
<xsl:template name="tab">
<xsl:param name="ancestors"/>
<xsl:for-each select="$ancestors">
<xsl:text>	</xsl:text>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
