You're using XSLT 2.0 so you can write $NO_BLOCK_ELEMENTS and
$SAME_ATTRIBUTES as stylesheet functions returning a boolean:

<xsl:function name="f:is-no-block-element" as="xs:boolean">
  <xsl:param name="n" as="element()"/>
  <xsl:sequence select="not(self::blockquote|self::center...)"/>
</xsl:function>

match="*[is-no-block-element(.)]"

Alternatively, many of the elements listed have a schema type of Inline in
the XHTML schema, so you could refer to them collectively as element(*,
Inline) if you import the schema.

The test string-join(@*,'xx') = string-join(current()/@*,'xx') looks wrong -
it's relying on the order in which attributes are returned by @*, which may
vary from one element to the next.

It looks to me as if your code could also benefit from using
<xsl:for-each-group group-adjacent="...">
